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
