In the figure, a force of magnitude 10.4 N is applied to a block of mass m2= 1.1 kg. The force is directed up an incline plane with an angle of 31.7°. The box is connected by a cord to another block of mass m,= 3.5 kg on the floor. The floor, plane, and pulley are frictionless, and the masses of the pulley and cord are negligible. What is the tension in the cord ?in N m2
