Conserve the Potential and Kinetic energy at Height “H” above projection point and “H” below the projection point.
Apply the Velocity condition at both heights given as per the question.
You will get velocity at height “H” above projection point. Find initial velocity (at projection point).
Find maximum height by third equation of motion, put final velocity equal to zero.
Answer shall be equal to (5/3)H.

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.
