A rubber ball of mass 100 g and radius 5 cm is submerged in water to a depth of 1 m and released. To what height will the ball jump up above the surface of water ? (Take `g= 10 m s^(-2))`

A rubber ball of mass m and radius r is submerged in water to a depth h and released. What height will the ball jump up to above the surface of the water? Neglect ther resistance of water and air. Take water density rho .

A ball of mass m and density rho is immersed in a liquid of density 3 rho at a depth h and released. To what height will the ball jump up above the surface of liqud ? (neglect the reistance of water and air).

A wooden ball of density D is immersed in water of density d to a depth h//2 below the surface of water and then relased. To what height will the ball jump out of water ?

A rubber ball of mass 10 gram and volume 15 cm^3 is dipped in water to a depth of 10m. Assuming density of water uniform throughtout the depth, find (a) the ac celeration of the ball, and (b) the time taken by it to reach the surface if it is relased from rest. (Take g =980 cm//s^2)
