JEE Mains · Physics · STD 11 - 3.2 motion in plane
Projectiles \(A\) and \(B\) are thrown at angles of \(45^{\circ}\) and \(60^{\circ}\) with vertical respectively from top of a \(400 \mathrm{~m}\) high tower. If their ranges and times of flight are same, the ratio of their speeds of projection \(v_A: v_B\) is _______.
- A \(1: \sqrt{3}\)
- B \(\sqrt{2}: 1\)
- C \(1: 2\)
- D \(1: \sqrt{2}\)
Answer & Solution
Correct Answer
(A) \(1: \sqrt{3}\)
Step-by-step Solution
Detailed explanation
For \(\mathrm{u}_{\mathrm{A}} \& \mathrm{u}_{\mathrm{B}}\) time of flight and range can not be same. So above options are incorrect.
