JEE Advanced 2021 Paper 1 · Q05 · Projectile Motion

Correct answer:0.50

Solution

At the highest point the projectile splits into two equal masses. One mass falls vertically and reaches the ground in 0.5 s. Since both halves start at the same height with zero vertical velocity (the velocity at the top is purely horizontal), they undergo identical free fall and take the same time to land. Hence t = 0.50 s.
