Question

A huge rectangular compartment falls vertically down with acceleration $a$. A gun fixed at corner $P$ requires to hit $Q$. The bullet fired by it will hit $Q$ if

• A. $a=g$
• B. $a>g$
• C. $a<g$
• D. any of $\left(A\right),\left(B\right)$ or $\left(C\right)$

Answer 1

Answer: (A)

$a=g$

When $a=g$ we see that this is the case of free fall and that the body has no net force acting on it. So the bullet will not get deviated from its path and hit Q. Thus A is the right answer.
