The normal reaction for the block on the plane is mgcos? .

The contact force between them is the friction(f)=µmgcos?

µmgcos? .

If the speed is to be constant then there shouldn't be no accelaration..The condition is tan(angle of inclination of the inclined plane)=coefficient of friction.

since the block is moving with constant velocity that means net force acting on the body is 0..

friction force(f) = mgsin@ ...............1

f = u(normal reaction)

f =uN

mgsin@ = uN

N = mgsin@/u (contact force)

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.
