Question

A projectile thrown with a speed $v$ at an angle $\theta$ has a range $R$ on the surface of earth. For same $v$ and $\theta$, its range on the surface of moon will be

• A. $R/6$
• B. $\mathbf{6R}$
• C. $R/36$
• D. $36R$

Answer 1

Answer: (B)

$\mathbf{6R}$

Answer 2

Range is given by $R = \frac{u^{2}\sin 2\theta}{g}$

On moon $g_{m} = \frac{g}{6}$. Hence $R_{m} = 6R$
