उत्तर
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.
