A 107-kg box on the right and a 43-kg box on the left are tied together by a horizontal cable. The 107-kg box is acted upon by an external force of 598 N to the right. The frictional force exerted by the floor on the 107-kg box is 30 N and the frictional force exerted by the floor on the 43-kg box is 16 N. What is the magnitude of the tension in the connecting cable?
