$981 \text{J}$

#### Explanation:

The formula for potential energy of a body, here denoted as ${E}_{p}$, is ${E}_{p} = m g h$, where:

$m$ is the mass of the body

$h$ is the height to which it is raised

$g$ is the acceleration due to gravity.

In our situation, $m = 50 \text{kg}$, $h = 2 \text{m}$, and on Earth, the acceleration due to gravity is always $9.81 {\text{m"/"s}}^{2}$.

Inputting these, we get:

${E}_{p} = 50 \cdot 2 \cdot 9.81$

${E}_{p} = 981 \text{J}$

$981 J$

#### Explanation:

Potential energy is given by the formula

$G . P . E . = m g h$

$m$ is the mass of the object in kg

$h$ is the height of the object in m

$g$ is the gravitational acceleration on Earth, which is $9.81 m \text{/} {s}^{2}$.

$\therefore G . P . E . = 50 \cdot 2 \cdot 9.81 = 981 J$
