Gravitational Potential & Energy question from JEE Main 2023 (11 Apr, Shift 2)

Q8JEE Main 2023 · 11 APR · SHIFT 2Easy

Gravitational Potential & Energy

If $V$ is the gravitational potential due to sphere of uniform density on its surface, then its value at the center of sphere will be:-

Show answer and solution

Answer: (a)

Surface: $V = -\frac{GM}{R}$ .
Centre of a uniform solid sphere: $V_c = -\frac{3GM}{2R}$ .
$V_c = \frac{3}{2}V$
So the answer is (a) $\frac{3V}{2}$ .
