MCQ
If the initial velocity of a projectile be doubled, keeping the angle of projection same, the maximum height reached by it will
- ARemain the same
- BBe doubled
- ✓Be quadrupled
- DBe halved
✓
Answer
Correct option: C.
Be quadrupled
c
(c) $H = \frac{{{u^2}{{\sin }^2}\theta }}{{2g}}\,$
(c) $H = \frac{{{u^2}{{\sin }^2}\theta }}{{2g}}\,$
$\therefore \,\,H \propto {u^2}.$
If initial velocity be doubled then maximum height reached by the projectile will quadrupled.
