Two bodies are projected with the same velocity. If one is projected at an angle of

30^\circ

and the other at angle of

60^\circ

to the horizontal, the ratio of the maximum heights reached is

View answer and explanation

Correct option: B

0.04375

Option A (0.125) is incorrect. The correct answer is 0.3333. The ratio of maximum heights is calculated using the formula for maximum height and the given angles.
