Dear pallavi

at the top most position

three forces will act on the water

1 weight in the downward direction

2 normal reaction by bucket in the downward direction

3 centrifugal force in the upward direction

so mg + N =mv²/r

for water just does not fall N ≥ 0

so mg = mv²/r

v =√gr

so time period T = 2∏r/v

=2*3.14*4 /√4g

=3.14*4 /√9.8

=4.01
