Question

Water drops fall at regular intervals fro a tap which is 5 m above ground.The third drop is leaving

Answer 1

Answer:

Given:

Height =h=5m

To calculate time taken by first drop to reach ground:

u=0m/s, t=T

so,

s=ut+1/2at²

5=0+1/2aT²-----(1)

Time taken by second drop will be T/2

Therefore, its distance from tap

h=0+1/2(aT²)/4       ------------(2)

divide equ (ii) by equ (1)

h/5=1/4

h=1.25m

therefore H-h=5-1.25=3.75m

Option E is the correct answer.
