Question

A body of mass $6kg$ is kept at a height of $5m$ from the surface of earth. Find the potential energy of the body. Take $\left(g=10m{s}^{-2}\right)$

Answer 1

Step 1: Given data

Mass of the body, m = $6kg$

Height at which it is kept, h = $5m$

Acceleration due to gravity, g = $10m{s}^{-2}$

Step 2: Finding potential energy

Potential energy (P.E) $=mgh$ where m= mass; h= height; g = acceleration due to gravity

$$\begin{gathered} P.E=6\times 10\times 5 \\ P.E=300J \end{gathered}$$

Hence the potential energy of the body is $300J$.
