If the finger is pushing but not hard enough, neither block will move. By Newton's 2nd law, for any object that is not accelerating, the forces in each direction must balance. Write the equations for the balance of the forces in the horizontal and vertical directions for block A and for block B (four equations). Start with the force exerted on block A in the horizontal direction.
