Since external force is zero so conservation of momentum will take placethen0 = p\hat{i} + 2p\hat{j} + p3So |p3| = \sqrt{5}p|p2| = 2pand m2 = m3and kinetic energy is given by E = p2/2mSO E2/E3 = p22/p32 = 4/5Hope it clears. If you like anser then please approve it.

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.
