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

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