JEE Main 2024 — 5 April, Shift 1 — Question 45

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:

Option A:
$1: 1$
Correct
Option B:
$2: 1$
Option C:
$\sqrt{3}: 2$
Option D:
$1: 2$

Answer: A

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
