Q20Short answer
The weight of any person on the moon is about 1/6 times that on the earth. He can lift a mass of 15 kg on the earth. What will be the maximum mass, which can be lifted by the same force applied by the person on the moon?
Show answer
ge = g and gm = g6 Force applied to lift a mass of 15 kg at the earth, F = m ge = 15 ge N Therefore, the mass lifted by the same force on the moon, 15 g m =F gm = g = 90 kg g × R2 mass g × R2
