- A charge Q is uniformly distributed through out the volume of a dielectric sphere of radius r
. A charge Q is uniformly distributed through out the volume of a dielectric sphere of radius r
A cavity of radius r/2 created inside the sphere as shown in the figure. The electric potential at a point (on the line passing through the centre of the cavity) distance 3r/2 from the centre of the sphere is
Best Answer
Ans: C
Sol: v = v0 - v
where v0 = potential due to whole sphere and
vc is potential due to sphere at the place of cavity
