Question
The weight of an object changes from place to place though its mass is constant.
✓

Answer

i. Mass is a fundamental quantity whose value remains same everywhere. Hence, the mass of an object is same everywhere in the universe.
ii. Weight of an object is product of mass and gravitational acceleration, i.e., $W = F = mg$
iii. As the weight depends on the value of acceleration due to gravity (g). Since value of g changes from place-to-place, the weight of the object is different at different places.
