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

Question:

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.

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

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