Question

Positive charge Q is distributed uniformly along the *x*-axis from x=0 to x=a. A positive point charge q is located on the positive *x*-axis at x=a+r, a distance r to the right of the end of Q.

Calculate the *x*-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, r, and and appropriate constants.

Calculate the magnitude of the force that the charge distribution Q exerts on q.

Express your answer in terms of the variables Q, q, a, r, and appropriate constants.

Calculate the direction of the force that the charge distribution Q exerts on q.
