Gravitational P.E. = m × gravitational potential U = mV So the graph of U will be same as that of V for a spherical shell.

Q. A shell of mass $M$ and radius $R$ has a point mass $m$ placed at a distance $r$ from its centre. The gravitational potential energy $U (r)$ vs $r$ will be

Gravitational $P . E . = m \times$ gravitational potential

$U = mV$

So the graph of $U$ will be same as that of $V$ for a spherical shell.

Q. A shell of mass M and radius R has a point mass m placed at a distance r from its centre. The gravitational potential energy U(r) vs r will be

Gravitational P.E.=m× gravitational potential U=mV So the graph of U will be same as that of V for a spherical shell.
