Question
The mass of a body on earth is 10 Kg, acceleration due
to gravity, g (e) is 10 m/s² . If acceleration due to gravity on the moon is g (m) 6 m/s² , then the mass of the body on moon will be?Solution
Mass of a body is independent from the force of gravity. It is the weight which changes with the force of gravity and acceleration due to it. Hence, the mass of body will remain same on moon as on earth. Hence, option C is correct.
