A block of mass \( m \) is lying at a distance \( r \) from a spherical shell of mass \( m \) and radius \( r \). Then :
Figure \( 6.94 \)
(A) Only gravitational field inside the shell is zero
(B) Gravitational field and gravitational potential both are zero inside the shell
(C) Gravitational potential as well as gravitational field inside the shell are not zero
(D) Can't be ascertained.
