A hollow conducting sphere of inner radius r and outer radius 2R is given charge Q as shown in figure, then the

Answer»

POTENTIAL at A and B is same.
potential at O and B is same.
potential at O and C is same.
potential at A,B,C and O is same.

Solution :a.,b.,c.,d.
points `A` and `B` LIE within the same metal HENCE `V_(A)=V_(B)`. The potential inside a HOLLOW sphere is same as potential at the surface, hence `V_(A)=V_(B)=V_(C)=V_(0)`.
