A hollow spherical shell is compressed to half its radius. The gravitational potential at the centre

Question

A hollow spherical shell is compressed to half its radius. The gravitational potential at the centre (A) increases (B) decreases (C) remains same (D) during the compression increases then returns at the previous value at the previmis value

V =-( GM / r ) Due to the negative sign, when the radius is halved the potential decreases.

Q. A hollow spherical shell is compressed to half its radius. The gravitational potential at the centre

increases

decreases

remains same

during the compression increases then returns at the previous value at the previmis value

$V = - \frac{GM}{r}$
Due to the negative sign, when the radius is halved the potential decreases.

V=−rGM​ Due to the negative sign, when the radius is halved the potential decreases.
