Question

A solid conducting sphere of radius R has a charge Q on itssurface; the sphere is concentric with a larger, thick conductingspherical shell with inner radius R1, outer radius R2 and netcharge -Q. Find the electrostatic potential for a) r > R2 b) R1< r < R2 c) R < r < R1 d) r < R A solid conducting sphere of radius R has a charge Q on itssurface; the sphere is concentric with a larger, thick conductingspherical shell with inner radius R1, outer radius R2 and netcharge -Q. Find the electrostatic potential for a) r > R2 b) R1< r < R2 c) R < r < R1 d) r < R

Explanation / Answer

A solid conducting sphere of radius R has a charge Q on itssurface; the sphere is concentric with a larger, thick conductingspherical shell with inner radius R1, outer radius R2 and netcharge -Q. Find the electrostatic potential for a) r > R2 b) R1< r < R2 c) R < r < R1 d) r < R

in the case of a spherical charged conducting sphere for aninternal point (r < R)potential every where inside is same,constant maximum and equal to value at the surface.
V=1/4o q/r
for any external point ,
V=1/4o q/r
