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:
- 1:1
- 2:1
- \(\sqrt3:2\)
- 1:2
The Correct Option is C
Solution and Explanation
The work done by gravity is independent of the path taken. It depends only on the change in vertical displacement. Therefore, in both cases (pulled straight up and along the ramp), the work done remains the same as the vertical displacement is the same.
