The electric potential due to charge, q is:
For r > r2
Let's take the net charge at the center of the concentric shells to be Q1 + Q2
Two concentric, spherical conducting shells have radii r1 and r2 and charge Q1 and Q2, as shown below.
Let r be the distance from the center of the sphere.
a) from the electric field obtained, determine the electric potential in the region r>r2 and r2>r>r1.
