Question

A spherical conductor has a radius of 14.0 cm and a charge of 31.0 C. Calculate the electric field and the electric potential at the following distances from the center.

(a) r = 9.0 cm

For points on the surface and outside, the sphere of charge behaves like a charged particle located at its center. Inside a conductor when charges are not moving, the electric field is zero and the potential is uniform Part 3 of 6 Analyze (a) Inside the conductor, the electric field is zero, so we have The potential is uniform inside the spherical conductor of radius R. Since the potential same value at has the the surface of the sphere and the same value as if the charge were point charge at a distance equal to the a radius of the sphere, we calculate it from the following. 99 x 109 N m2/c2 x 10-6 c x 106 v mit Skip u cannot come back ed Help?

Explanation / Answer

a) E = 0

b) v = k*Q/R

= 9*10^9*31*10^-6/0.14

= 1.99*10^6 volts
