Inside a uniform thin spherical shell of mass $M$ and radius $R$, the gravitational field and potential at a point halfway between the centre and the shell are respectively
Answer: (C) $0$ and $-\dfrac{GM}{R}$
Concept. Inside a shell the field is zero, so the potential equals its surface value.
Step 1. Values. $E = 0$, $V = -\dfrac{GM}{R}$.
Answer. $0$ and $-\dfrac{GM}{R}$ (Option C).
