Sol. T = 2π √R base 2^3/gR base 1^2 Or T^2 = 4π^2 R base 2^3/gR base 1^2 Or g = 4π^2/T^2 R base 2^3/gR base 1^2 ∴ Acceleration due to gravity of the planet is = 4π^2/T^2 R base 2^3/gR base 1^2

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.
