A cane filled with water is revolved in a vertical circle of radius 4m and the water just does not fall down the time period of revolution will be

Answers : (2)


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

But the force was not given with the question. There was no numerical value, just ‘F’. I’d be happy if you gave me the shortcut, though.

a body is projected vertically up with a velocity 60m/s, the % of its initial ke converted into pe after 3 seconds?
at 3 seconds , h = 60*3 – 0.5g*9 = > 135 meter. P.E. = mgh = >1350m K.E = 0.5m*3600 = > 1800m % = 1350m/1800m * 100 => 75%
