Question

Body is lifted by a man to height of 1 m in 30 seconds. Another man lifts the same mass to the same height in 60 seconds. The work done by them are in the ratio

Answer 1

here the ratio is 1:1 as work done against gravity is mgh which is independent of time

Answer 2

First man lifted the body in 30s but another man lift the body in 60s.So, the second man took 30s more to lift the body. But the ratio will be same as the height 1m and 1m=1: 1.
