JEE MAIN - Physics (2024 - 5th April Morning Shift - No. 1)
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 :

$$2: 1$$
$$\sqrt{3}: 2$$
$$1: 1$$
$$1: 2$$
Explanation
Work done in both cases is equal to $$-m g \Delta h$$
$$\therefore \quad \text { Ratio }=1: 1$$
