Dear student
Force = m* g Newton
F = 2 * 9.8 = 19.6 N
Now
Work done = m*g*h
= 2* 9.8 * 4 = 78.4 Joules

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.
