A projectile A is thrown at an angle of 30° to the horizontal from point P. At the same time, another projectile B is thrown with velocity v 2 upwards from the point Q vertically below the highest point. For B to collide with A , ( v 2/ v 1) should be (A) 1 (B) 2 (C) (1/2) (D) 4

This happen when vertical velocity of both are same. ∴ v2=v1 sin 30° or (v2/v1)=(1/2)

Q. A projectile $A$ is thrown at an angle of $3 0^{\circ}$ to the horizontal from point $P$ . At the same time, another projectile $B$ is thrown with velocity $v_{2}$ upwards from the point $Q$ vertically below the highest point. For $B$ to collide with $A, \frac{v _{2}}{v _{1}}$ should be

$\frac{1}{2}$

This happen when vertical velocity of both are same.
$∴ v_{2} = v_{1} sin 3 0^{\circ}$
or $\frac{v _{2}}{v _{1}} = \frac{1}{2}$
