Figure shows a thin plastic rod of length L = 13.5 cm and uniform charge 43.6fC.

(a) In terms of distance d, find an expression for the electric potential at point Pr.

(b) Next, substitute variable x for d and find an expression for the magnitude of the component Ex of the electric field at P1.

(c) What is the direction of E" relative to the positive direction of the x axis?

(d) What is the value of Ex at P1 for x - d = 6.20 cm?

(e) From the symmetry in Figure determine Ey atP1.
