Question

Two spheres have equal charges. Calculate the ratio of surface density
of charge if ihe ratio of the volume density of charge is 8: 64.​

Answer 1

The ratio of volume charge density of the first sphere to the second sphere is given by :

The surface charge density of sphere is given by :

For sphere 1 and 2 we get :

So, the ratio of the surface charge density of two sphere is 1:4.
