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 : 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.

Options

  1. A1:21: 2
  2. B3:2\sqrt{3}: 2
  3. C2:12: 1
  4. D1:11: 1

Correct answer

D. 1:11: 1

Step-by-step solution

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