POTENTIAL DUE TO A SYSTEM OF CHARGES

Superposition principle

By the superposition principle, the potential V at any point due to the total charge configuration is the sum of the potentials due to the individual charges

That is V = V1 + V2 + ... + Vn

True-False Question

Question 1

For a uniformly charged spherical shell, the electric field outside the shell is as if the entire charge is concentrated at the centre.

Question 2

The electric field inside the shell is zero. This implies that potential is also zero inside the shell.
