Question 54 of 183

A body of mass 50 kg50 \mathrm{~kg} is lifted to a height of 20 m20 \mathrm{~m} from the ground in the two different ways as shown in the figures. The ratio of work done against the gravity in both the respective cases, will be :

Show answer and solution

Answer: (D) 1:11: 1

Work done by gravity is independent of path. It depends only on vertical displacement so work done in both cases will be same.
