Question

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?

Answer 1

On earth Force applied by the man (F) on earth = m×g (m = mass)

on moon  g = `"g"/6` so, by same force he can m₁ `"g"/6` = mas om = 15 kg so, m = `15/56`

= 90 kg As Mass does not change at every place. It is a concerning quantity. So, 15 kg will be the maximum mass that can be lifted by the same force applied by the person on the moon.
