Physics

The correct statement is: An object at a certain height above the ground can have zero gravitational potential energy.

The gravitational potential energy is relative to the chosen reference point. If we choose the height of the object as the reference point, then its gravitational potential energy at that height will be zero. The potential energy depends on the chosen reference level.

Option A

The gravitational potential energy of an object on the ground is always zero.

This is not necessarily true. Gravitational potential energy is relative to a chosen reference point. If we choose the ground as the reference point, then the gravitational potential energy of an object on the ground would be zero. However, if we choose a different reference point (e.g., a height above the ground), the gravitational potential energy of the object on the ground would not be zero.

Option B

An object with a larger mass ...
