Answer 1

A group of skydiver are riding in a helicopter up to the spot form which they will jump. As they ride upwards. their gravitational potential energy increases.

Answer: Option A

Explanation:

Gravitational potential energy refers exerted energy on any object rising from the surface of Earth. It is the measurement of potential energy of any object depending on its position.

We can also define gravitational potential energy as the amount of energy required to raise an object to certain level from the surface of Earth or the work done to raise the object to some position from a position of reference. The formula for calculating the gravitational potential energy is

               $\text {Gravitational potential energy}=m g \Delta h$

Here, m is the object's mass, g -the acceleration and $\Delta h$ - the object's distance from the Earth's surface.

So from this formula, it can be confirmed that if the helicopter carrying skydivers are made to ride upwards, then their gravitational potential energy will increase as the distance of helicopter from the Earth's surface is increased on riding the helicopter upwards.
