Question

Consider a solid conducting sphere with an inner radius R1 surrounded by a concentric thick conducting spherical shell which has an inner radius R2 and outer radius R3. There is a charge Q on the sphere and no net charge on the shell. For all parts of this problem, we adopt the standard convention of setting the electric- potential at infinity to zero. Find the potential at A, where OA > R3. VA = kQ / R3 - kQ / R2 + kQ / a VA = 2 2 k Q / a VA = 0 VA = kQ / R2 + kQ / a VA = 2kQ / a VA = kQ / a VA = kQ / R2 - kQ / R1 + kQ / a VA = 2kQ / a VA = 2kQ / R1 VA = kQ / R3 + kQ / a

Explanation / Answer

6 KQ/a is correct as net potential due to shell will be zero
