Weight of the body on Earth = 98 N. Acceleration due to gravity on Earth = 9.8 m/s2. Let 'm' be the mass of the body on Earth. m = W/g m = (98/9.8) = 10 kg Thus, the mass of the body is 10 kg, which always remains constant. (a) Mass on moon = mass on Earth = 10 kg (b) Let weight on moon is W'. W' = mass × acceleration due to gravity on the Moon. [Given, acceleration due to gravity on the Moon = 1.6 m/s2] W' = 10 × 1.6 =16 N. |
