Since external force is zero so conservation of momentum will take place
then
0 = p
+ 2p
+ p3
So |p3| = 
|p2| = 2p
and m2 = m3
and kinetic energy is given by E = p2/2m
SO E2/E3 = p22/p32 = 4/5
Hope 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.
