The weight of a body of mass 6.0 kg on moon is 10 N. If a boy of mass 30 kg goes from earth to the moon surface, what will be his(a) mass,(b) weight ?

Answer»

(a) Mass remains same it does not change

So mass of boy 30 kg on earth = 30 kg on moon surface

(b) Weight of boy on moon becomes 1 / 6

∴ 30 kg boy will weight 30 x 1/6 = 5 kg

1 kg = 10 N ⇒ 5 × 10 N = 50 N

∴ Weight of boy on moon surface = 50 N
