This assignment is very easy, and it will not take more than one hour to complete it. So please try your best to do it.

The instructions are a bit long because I wanted to explain each one on it and to know what you have to do for this assignment. I provide all the instructions for this assignment, and I think all of them are very clear and simple to understand.

There are three short videos you have to watch to know what you need to do and to make you understand everything is required to do.

Each video has a link front of it so please make sure all the three videos are working with you puls each of them are different

Iβll give you the steps for this assignment to make it easy for you. Please read the instructions and watch the three videos carefully to know what you gonna do and make it easy for you.

1) The module is dealing with charges and their interactions with each other. The student will:

Review some basic concepts of Coulomb’s Law.

Analyze SIMULATED Coulomb force data in Excel using both the trendline function and LINEST.

Demonstrate fundamental knowledge of vector diagrams with regards to charge interactions.

Note: Please review your textbook for Coulomb’s Law and charge interactions. It might also be helpful to review basics of force diagrams. These concepts may be used to address some key questions.

Watch the instructional (brief) video

Read over and prepare your spreadsheet. [Ask questions if something is NOT clear!]

Collect data from the macro system and then the micro system. Make sure there is a separate tab for each in the spreadsheet.

Follow the analysis instructions. Presentation is key in this module as well as reviewing the concepts of vectors.

3) In these calculations, the Coulomb constant has a value of 8.99Γ109πβ
π2πΆ2

8.99Γ109Nβ
m2C2

Part I (Label the tab “macro”): This is the macroscopic data. Note that: π1=π2=π.q1=q2=q.

Starting in cell D2, record all of your force measurements down the D column. In cell A1, record the initial position of q1. In cell A2, record the initial position of q2. The difference in those positions is the first separation between the charges. Place this value in B2. In cell B3, type (without quotes) “B2 0.1”. Hit enter. Copy the formula down to the last force measurement. Finally, in cell C2, type “B2/100”, and copy the formula down.

1.Place column labels in cell 1. In cell C1, it is π(π)r(m). In D1, it is πΉ(π)F(N).

2. Plot πΉ(π)π£π .πF(r)vs.r . Make sure you insert the correct graph! It looks like in inverse-square curve. Label the graph for presentation. Afterwards, run a trendline by right-clicking the data. Chose power fit. Place the equation on the graph and enhance the size. Note the power of the fit. Record and label on the spreadsheet close to the graph the power obtained and the coefficient. Note: Do NOT run a LINEST or linear fit here!!!!!

For this analysis, using the Coulomb equation and this coefficient, calculate q. Record this value in SI based units as well as in micro-Coulombs.

Part II (Label a new tab “micro”): You are given that π2=4πq2=4e. Note that this scale is now in picometers.

Starting in cell D2, record all of your force measurements down the D column. In cell A1, record the initial position of q1. In cell A2, record the initial position of q2. The difference in those positions is the first separation between the charges. Place this value in B2. In cell B3, type (without quotes) “B2 0.1”. Hit enter. Copy the formula down to the last force measurement. Finally, in cell C2, convert first value to meters, and copy the formula down.

1.Place column labels in cell 1. In cell C1, it is π(π)r(m). In D1, it is πΉ(π)F(N).

2. Plot πΉ(π)π£π .πF(r)vs.r . Make sure you insert the correct graph! It looks like in inverse-square curve. Label the graph for presentation. Afterwards, run a trendline by right-clicking the data. Chose power fit. Place the equation on the graph and enhance the size. Note the power of the fit. Record and label on the spreadsheet close to the graph the power obtained and the coefficient. Note: Do NOT run a LINEST or linear fit here!!!!!

For this analysis, using the Coulomb equation and this coefficient, calculate π1q1. Record this value in SI based units as well as in micro-Coulombs. Also, record the polarity. Is it is negative or positive ion? How do you know?

4. Plot πΉ(π)π£π .1π2F(r)vs.1r2. Is it linear? Label the graph for presentation. Run a LINEST by highlighting a 2 x 5 matrix starting around cell A15 or so. Record the value of the slope and the uncertainty (e.g. 2.5Β±0.12.5Β±0.1).

For this analysis, using the slope and the Coulomb constant, calculate π1q1. Record this value in SI based units as well as in micro-Coulombs. Also, compare with your first calculation and comment.

Part III (Create a tab called “summary”): Insert large text boxes to type in.

In the summary tab, address these questions:

From the data (you) collected, does the power fit indeed illustrate the inverse-square Law?

Suppose you placed another charge (π3q3) on the opposite end of the ruler of (a) equal value as π1q1and with the same sign and (b) a charge π3=2π1q3=2q1 .

Describe how the force on π2q2 would look as a function of position starting at the original point as before, and then moving towards the right for both scenarios (a) and (b)? Analyze one scenario at a time! Take a stab at it. How would you begin to investigate this?

Suppose you were in a lab doing these measurements, assuming well-calibrated equipment, list some random errors you would encounter.

## velocity question

A proton is flying through space with a velocity of 100,000 m/s. It starts off in a region of space with no electric potential, heading for a different region of space with a 40-Volt electric potential. Solve this problem using conservation of energy. Look up the charge and mass of the proton as needed.

A) Show a calculation which determines whether or not the proton can make it to the 40-Volt region.

B) If the proton *can* make it to the 40-Volt region, find the proton’s final velocity when it gets to this region. But, if the proton *cannot* make it, instead find the highest electrical potential it can get to (before it stops).

## physics home work

Physics Assignment Help An electron is traveling horizontally with speed vx= 40 km/swhen it passes into a region of uniform, downward electricfield with magnitude E = 950 N/C. The field is generated bytwo horizontal plates with equal (and opposite) charges thatare separated by a distance d = 2.5 mm. When the electronenters this region, it is midway between the two plates. Whatangle ? does the electronβs velocity vector make with respectto the horizontal when it crashes into one of the plates? Forthe limits check, investigate what happens to ? as the platesbecome extremely close together (d ?0). Note: the effects ofgravity can be neglected in this problem.
