Chapter 19.1, Problem 5TH
A thin semicircular rod like the one in problem 4 is broken into two halves. The top half has a total charge +Q uniformly distributed along it, and the bottom half has a total charge −Q uniformly distributed along it.
On the diagram, indicate the direction of the net electric force on a positive test charge placed in turn at points A, B, and C. Explain how you determined your answers.

The angle between the two short sides is 90°. The two short sides of the triangle have length a. Investigate the net force on the charge (q) in the lower right corner due to the other two charges (q, -q). As needed, assume a right-handed coordinate system shown below:
(A) What is the magnitude of the net force on the charge in the lower right corner due to the other charges? Use symbols for the answer.
(B) Make a sketch of the net force vector on the x-y axes below with the tail of the arrow at the origin. Label the angle with the x-axis. What quadrant does the vector lie in? Your picture should indicate the correct quadrant.
Given the diagram where q1 is the positive and q2 is the negative charge, while q0 is (0,d), answer the following:
a.) What is the net electric field at q0?
b.) What would be the electric force acting on charge q0?
Positive electric charge is uniformly distributed along the y-axis with a linear charge density l.
Consider the case where charge is distributed only between points y = +a and y = -a. For points between the +x-axis, graph the x-component of the electric field as a function of x, Ex (x), for values x = a/2 and x = 4a.
Consider instead the case where charge is distributed along the entire y-axis with the same charge density l. Using the same graph as in part (a), plot the x-component of the electric field, Ex (x), as function of x for values of x between x = a/2 and x = 4a.
