JEE Main 29 July 2022, Shift 2, Physics Q43

Question 43 of 90 in this shift, Physics question 13 of 30, Section A.

A ball is released from a height h. If

t_1

and

t_2

be the time required to complete first half and second half of the distance respectively. Then, choose the correct relation between

t_1

and

t_2

(1) $t_1=(\sqrt{2})t_2$
(2) $t_1=(\sqrt{2}-1)t_2$
(3) $t_2=(\sqrt{2}+1)t_1$
(4) $t_2=(\sqrt{2}-1)t_1$ Official answer
