potential energy = -2 x K.E = -2 x 1/2m.v2 = -mv2.
To just escape gravitational pull , total mechanical energy must be zero. so K.E will equal to mv2.
Thanks and Regards

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.
