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 kQ / a VA = 0 VA = kQ / R2 + kQ / a VA = 2 kQ / 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
