Q, a, x, r, and appropriate constants.


Part B
Calculate the y-component of the electric field produced by the charge distribution Q at points on the positive x-axis where x>a.
Express your answer in terms of the variables
Q, a, x, r, and appropriate constants.

Part C
Calculate the magnitude of the force that the charge distribution Q exerts on q.
Express your answer in terms of the variables Q.
