MCQ
The projectile attains maximum height when it is projected at an angle of
  • A
    $30^{\circ}$
  • B
    $45^{\circ}$
  • $90^{\circ}$
  • D
    $120^{\circ}$

Answer

Correct option: C.
$90^{\circ}$
(C)
It is to be noted that, as range of projectile varies with $\sin (2 \theta)$, its maximum value IS obtained at $\theta=45^{\circ}$. However, the maximum height of projectile varies with $\sin ^2 \theta$, its maximum value is obtained at $\theta=90^{\circ}$.
