Question

If a rock is brought from the surface of the moon

• A. its mass will change
• B. its weight will change, but not mass
• C. both mass and weight will change
• D. its mass and weight will remain the same

Answer 1

The correct option is B its weight will change, but not mass

Mass of a body always remains constant. Weight depends on the gravitational acceleration $\left(g\right)$, which differs. Since acceleration due to gravity on moon is $(1/6{)}^{th}$ of that on earth. So, the weight of the rock brought from the surface of the moon will change but mass remains constant.
