Q. A particle when thrown, moves such that it passes from same height at $2$ and $10s$, the height is
A) $g$
B) $2g$
C) $5g$
D) $10g$
Explanation
(d) If $t_{1}$ and $t_{2}$ are the time, when body is at the same height then,
$h = \frac{1}{2}gt_{1}t_{2} = \frac{1}{2} \times g \times 2 \times 10 = 10\ g$
