Reference no: EM13687678

Solve the given question:

Question: A solid disk of radius R = 11 cm lies in the y-z plane with the center at the origin. The disk carries a uniformly distributed total charge Q = 65 µC. A point P is located along the x-axis a distance 25 cm from the origin.

Part a. Write an equation for the surface charge density in terms of the total charge and radius of the disk.

Part b. Consider a thin ring of the disk of thickness dr located a distance r from the center. Write an equation for the charge in this thin ring in terms of Q, R, r, and dr

Part c. Calculate the electric potential at P in units of kilovolts, kV.

Part d. Calculate the electric field at the point P in units of mega Newton's per coulomb.

Your answer must be supported by illustrations.
