Homework Statement
In non uniform spherical shell of mass 'm' and radius R (here E is gravitational intensity) which of the following are wrong;
(A) E = 0 (r<R)
(B) ∫ E.dS = 0 on any closed surface inside the shell
(C) E can not be zero at any point inside the shell
(D) Gravitational potential is zero at any point inside the shell.
