The net force on the rope will be equal to 1.6 N.
The net force can be defined as the vector sum of forces acting on a body. The net force can be described as a single force providing same the effect as the original forces on the body's motion.
The net force acting on an object becomes the resultant force. The net force has the same effect on the motion as all actual forces taken together by the object.
Given, the applied force by Mrs. Cadillac's class = 50.4 N
The applied force by Mrs. Barr's class = 48.8 N
The net force = 50.4 N + (-48.8N) = 1.6 N
