Projectiles A and B are thrown at angles of $45^{\circ}$ and $60^{\circ}$ with vertical respectively from top of a $400 m$ high tower. If their ranges and times of flight are same, the ratio of their speeds of projection $v _A: v _B$ is :
[We changed options. In official NTA paper no option was correct.]
(1) $1: \sqrt{3}$
(2) $\sqrt{2}: 1$
(3) $1: 2$
(4) $1: 1$

Answer: (4)
Solution:
For $u _A \& u _B$ time of flight and range can not be same. So above options are incorrect.
