Q. A body, thrown upwards with some velocity reaches the maximum height of $50\ m$. Another body with the double the mass thrown up with double the initial velocity will reach a maximum height of
A) $100\ m$
B) $200\ m$
C) $300\ m$
D) $400\ m$
Explanation
(b) $H_{\max} \propto u^{2}$, It body projected with double velocity then maximum height will become four times $i.e.$ $200\ m$
