MCQ
A projectile fired with initial velocity $u$ at some angle $\theta$ has a range $R$. If the initial velocity be doubled at the same angle of projection, then the range will be
- A$2 R$
- B$R / 2$
- C$R$
- ✓$4 R$
✓
Answer
Correct option: D.
$4 R$
(d) $\quad R=\frac{u^2 \sin 2 \theta}{g} \therefore R \propto u^2$. If initial velocity be doubled then range will become four times.
