JEE Main 6 April 2024, Shift 2, Physics Q33

Question 33 of 90 in this shift, Physics question 3 of 30, Section A.

A body projected vertically upwards with a certain speed from the top of a tower reaches the ground in t1t_1. If it is projected vertically downwards from the same point with the same speed, it reaches the ground in t2t_2. Time required to reach the ground, if it is dropped from the top of the tower, is :
  1. (1)t1t2\sqrt{t_1t_2}Official answer
  2. (2)t1+t2\sqrt{t_1+t_2}
  3. (3)t1−t2\sqrt{t_1-t_2}
  4. (4)t1t2\sqrt{\frac{t_1}{t_2}}
