water drops fall at regular intervals from a roof. at an instant when a drop is about to leave the roof the separations between three successive drops below the roof are in what ratio? please answer fast....
The answer is 5:3:1
Let the interval be t. Then the first drop of the three has left t sec before, second has 2t sec and the third one at 3t sec. Then the distances covered by them respectively are
0(Drop about to fall), 1/2(t2) (I drop) , 2t2 (II drop), 9/2 t2 (III drop)
