Question : Water drops fall from a tap on the floor 5m below at regular intervals of time, the first drop striking the floor when the fifth drop begins to fall. The height at which the third drop will be, from ground, at the instant when first drop strikes the ground, will be (g =10ms−2 )

(A) 1.25 m

(B) 2.15 m

(D) 3.75 m

Answer : option (D)

Solution :

Water drops fall from a tap on the floor 5m below at regular intervals of time, the first drop striking the floor when the fifth drop begins to fall. The height at which the third drop will be, from ground, at the instant when first drop strikes the ground, will be (g =10ms−2 )
