If a rock is brought from the surface of the moon to the earth, then

its mass will change.

its weight will change but not its mass.

both mass and weight will change.

both mass and weight will remain the same.

Verified by Experts

The correct Answer is:

If a rock is brought from the surface of the moon to the earth, its weight will change but not its mass. Mass is a invariant physical quantity whereas weight of a body (w = mg) is variable as the value of acceleration due to gravity (g) changes.
