Two bodies A and B of equal masses are kept at heights of $h$ and $2h$ respectively. What will be the ratio of their potential energies?
Let $m$ be the mass of the two bodies.
As given, heights of the bodies A and B are $h$ and $2h$
We know the formula for potential energy $U=mgh$
Potential energy of body A $=mgh$ [$g$ is gravitational acceleration]
Potential energy of body B $=mg(2h)=2mgh$ [as body B is kept on $2h$ height]
Therefore, the ratio of the potential energies of the bodies A and body B $=\frac{U_A}{U_B}$
$=\frac{mgh}{2mgh}$
$=\frac{1}{2}$
$=1:2$
