A body of mass 50 kg is lifted to a height of 20 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:

Question

G1 Physics · Accepted Answer

Image Work done against gravity depends only on the change in vertical height: W = mgh Both paths raise the body through the same vertical height. Therefore, work done in both cases is the same. Ratio = 1 : 1
