Water drops fall at regular intervals from a roof. At an instant when a drop is about to leave the roof, the separations between $3$ successive drops below the roof are in the ratio:

Options:

Answer:

Solution:

If drops fall every $T$ seconds, the distances fallen by the last three drops are $\frac{1}{2} g T^{2}$ , $2 g T^{2}$ and $\frac{9}{2} g T^{2}$ , i.e. $s_{1}, 4 s_{1}, 9 s_{1}$ . The successive separations are $s_{1} : 3 s_{1} : 5 s_{1} = 1 : 3 : 5$ . Option C.
