Let be the density of ball and the density of water. Net retardation inside the water,
Hence, the ball will go upto the same depth below the water surface. Further, time taken by the ball to come back to water surface is,

We first assume that the drop formed at the opening is spherical because that requires a minimum increase in its surface energy. To determine the size, we calculate the net vertical force due to the surface tension when the radius of the drop is . When this force becomes smaller than the weight of the drop, the drop gets detached from the dropper.
After the drop detaches, its surface energy is
