From law of conservation of energy then k1+u1=k2+u2
At point a k1= 0, u1 = mgh where h =3r
at point b u2=0 , k2=1/2 mv2
We substitute in above equation we get v =root of 6gr

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
