A bucket containing water is tied to one end of the rope of length 2.5 m and rotated in a vertical circle in such a way that the water in it does not spill. What is the minimum velocity of bucket at which this happens and how many rotations per minute is it taking?

The minimum speed at the highest point will be ?gr because at the highet point theminimum speed when the  requried centripetal force is equal to the the weight of the water.
means mg=mv2/r
