A) 10 N
B) 2 N
C) 60 N
D) 120 N
Correct Answer: A
Solution :
In order to answer this question, the student must determine the net force acting on the rope. The total force on the rope toward the right is 60 N, i.e., applied by Mark. The total force on the rope toward the left is \[40\text{ }N+20\text{ }N=60\text{ }N,\]i.e., applied by Sandy and George. Hence, the net force on the rope is 60 N - 60 N = 0 N.
