Question

What would be the gravitational potential energy of an object whose mass is $\text{1 kg}$ and is at a height of $\text{10 m}$?

• A. 50J
• B. 49J
• C. 10J
• D. 98J

Answer 1

The correct option is D

98J

The energy possessed by a body due to its position is the potential energy.

Potential energy, PE $=m\times g\times h$
where, $m$ is the mass, $g$ is the acceleration due to gravity and $h$ is the height to which the body is raised.
$\therefore$ Potential Energy, PE $=m\times g\times h=1\times 9.8\times 10=98J$
