A sealed metal box of mass $5\text{ kg}$ is transported from sea-level Mumbai to a high mountain peak in Leh. What happens to its mass and weight?
  1. Mass remains $5\text{ kg}$, but weight decreases slightly.
  2. Both mass and weight increase.
  3. Mass decreases, but weight remains identical.
  4. Both mass and weight remain exactly identical.

Solution

Mass remains unchanged ($5\text{ kg}$), but weight decreases slightly at higher altitudes because gravity decreases with distance from Earth's center.
