Physics Problem Dealing with Cocentric Conducting Spherical Shells?

A spherical capacitor is formed from two concentric spherical conducting shells separated by vacuum. The inner sphere has radius 10.0 centimeters, and the separation between the spheres is 1.50 centimeters. The magnitude of the charge on each sphere is 3.30 nanocoulombs.



What is the magnitude of the potential difference DeltaV between the two spheres?

You might check out the source below. Here is the rough ideal.

The potential difference is going to be given by the line integral of the electric field between the conductors



dV = - Integral from 0.100 to 0.115 of E in gap

The electric field in the gap is given by gausses law, which says that Efield is just =kq/r^2 where q is charge of inner conductor.



so dv = - Int(kq/r^2) from 0.1 to 0.115



hope that helps
