Question

If the initial velocity of a projectile be doubled. Keeping the angle of projection same, the maximum height reached by it will

A

Remain the same

B

Be doubled

C

Be quadrupled

D

Be halved

Answer

Be quadrupled

Explanation

Solution

$H = \frac{u^{2}\sin 2\theta}{2g}$ $\therefore H \propto u^{2}$ [As $\theta =$ constant]

If initial velocity of a projectile be doubled then H will becomes 4 times.
