Q.
A mass $m$ is placed at a point $B$ in the gravitational field of mass $M$. When the mass $m$ is brought from $B$ to near point $A$, its gravitational potential energy will
A) Remain unchanged
B) Increase
C) Decrease
D) Become zero
Explanation
(c) Gravitational potential energy of a body in the gravitational field, $E = \frac{- GM\ m}{r}$. When $r$ decreases negative value of $E$ increase $ie$, $E$ decreases
