h=1/2g(t₁₊t₂)²

2h/g=(t₁+t₂)²------(1)

h/2=1/2gt₁²

t₁²=h/g---------(2)

From 1st and 2^nd

t₁²=(t₁+t₂)²/2

t₁=(t₁+t₂)/1.41

1.41t₁₌t₁+t₂

t₁=t₂/.41

t₁=2.414t₂

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.
