1.
The mass of a body on earth is 100kg.(acceleration due to gravity, ge=10m/s2). If acceleration due to gravity on moon is (ge/6), then the mass of the body on the moon is
Answer : C. 100 kg (Mass is indestructible.no matter where you are in the universe your mass will never change and Mass can never be zero)
