Force acting on the body will be equal to

F + mg = ma

Insert the above value in the equation ,

We get F = 19.6 N

Hope this helps

F = additional force acting on the body in down direction

m = mass of the body = 2 kg

g = acceleration due to gravity = 9.8 ms⁻²

a = acceleration in down direction = 19.6 ms⁻²

force equation for the motion of stone in down direction can be given using newton's second law as

F + mg = ma

inserting the above values

F + (2) (9.8) = (2) (19.6)

F = 19.6 N

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.
