    Suppose mass of water is m, radius of bucket r, and velocity v

    At the top, downward force on water is m while upward force is the centrifugal force = mv^2/r

    Hence in this case minimum value of centrifugal force must be mg so that water is not spilled

    That is : Minimum value of mv^2/r = mg

    Minimum value of v^2 = gr

    You can find minimum value of v now.
