Kinematics Question 694
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 $ , it’s range on the surface of moon will be
Options:
A) $ R/6 $
B) $ 6R $
C) $ R/36 $
D) $ 36R $
Show Answer
Answer:
Correct Answer: B
Solution:
[b] Range it’s given by $ R=\frac{u^{2}\sin 2\theta }{g} $
On moon $ g _{m}=\frac{g}{6} $ .
Hence $ R _{m}=6R $
