JEE Mains · Physics · STD 11 - 5. work,energy,power and collision
A body of mass \(50 \mathrm{~kg}\) is lifted to a height of \(20 \mathrm{~m}\) 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 \(1: 1\)
- B \(2: 1\)
- C \(\sqrt{3}: 2\)
- D \(1: 2\)
Answer & Solution
Correct Answer
(A) \(1: 1\)
Step-by-step Solution
Detailed explanation
Work done by gravity is independent of path. It depends only on vertical displacement so work done in both cases will be same. Option \((1)\) is correct
