Question

Write a Matlab code:

2. Using normalized units, the potential associated with a charge q1 is V = q1/r, where r is the distance from the charge. Consider a situation for which a positive unit charge is located at each of the points (-1, 0) and (1, 0). (a) Calculate and plot the resulting potential on an integer grid that is defined for x from -5 to 5, and for y from -5 to 5. Can you define the potential at (-1, 0) and (1, 0)? Why or why not? (b) Calculate approximate values of the x and y components of the normalized electric field at the points (-2, 0), (2, 0), (0, -2), (0, 2), (1, 1), and (-4, -2). Hints: You may do this problem using a spreadsheet, MATLAB, or a programming environment of your choice. If you use a finer grid, you will obtain better approximations to the electric field. 3. The Electric Dipole (10 points) Repeat question 2 for a situation in which a positive unit charge is located at (-1, 0) and a negative unit charge is located at (1, 0).
