A man of `50 kg` mass is standing in a gravity free space at a height of `10m` above the floor. He throws a stone of `0.5 kg` mass downwards with a speed `2m//s`. When the stone reaches the floor, the distance of the man above the floor will be

20m

9.9m

10.1m

10m

Text Solution

Verified by Experts

The correct Answer is:

Position of centre of mass `(m_(1)r_(1)= m_(2)r_(2)]`
`50x= 0.5 (10) rArr x= 0.1m`
Distance from the ground `=10 + 0.1= 10.1m`
