A positive point charge q is placed on the +y-axis at y = a, and a negative point charge –q is placed on the –y-axis at y = -a. A negative point charge –Q is located at some point on the +x-axis.
a. Draw a free-body diagram showing the forces that act on the charge –Q.
b. Find the x and y components of the net force that the two charges q and –q exert on –Q. (Your answer should involve only k, q, Q, a, and the x-coordinate of the charge -Q)
c. What is the net force on the charge –Q when it is at the origin ( x = 0 )?
