Vedclass · Answer

(B) Potential energy is given by the formula $U = mgh$.Here,$m$ is mass in $gm$,$g$ is acceleration due to gravity in $cm/sec^2$,and $h$ is height in $cm$.Substituting these units: $U = (gm) \cdot (cm/sec^2) \cdot (cm) = gm \cdot (cm^2/sec^2)$.This can be rewritten as $gm \cdot (cm/sec)^2$.Therefore,the correct option is $B$.
