Question

A thin spherical shell of radius R has charge Q spread uniformly over its surface.

Answer 1

A thin conducting spherical shell of radius R has charge +q spread uniformly over its surface. Using Gauss's law, derive an expression for an electric field at a point outside the shell. ... The variation of the electric field intensity E(r) with distance r from the centre for shell 0 ≤ r < ∞ is shown below.
