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?

Explanation

Here, `W_(m)=1/6W_(e)`
`:. g_(m)=1/6g_(e)`
Force applied by the person on lift a mass m
`F=m g_(e)=15g_(e)`
If he can lift a mass m' on moon by applying same force,then `F=m'g_(m)`
`F=m' g_(m)=15g_(e)`
`m'=15(g_(e))/(g_(m))=15xx6=90 kg`.
