Question

Ratio of surface charge densities of two spheres of equal radii having chaeges q and 3q respectively

Answer 1

Answer:

There are two non-conducting spheres having uniform volume charge densities and . Both spheres have equal radius R.

U=k×(4×pi×(R^2)×D)/R=4×pi×k×D×R. Hence the ratio would be R1/R2.
