since the train is moving with accn .the frame of train is non inertial solve the question according to train frame .take the pseudo force ma opposite to the direction of adue to pseudo force it moves towards left.

let the tension be T

mg=Tcosθ

ma=Tsinθ

divide the eqn

tanθ=a/g

θ=tan^-1(a/g)

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.
