Answer:
100 N
Step-by-step explanation:
Given that,
The force acting on the rope By Mrs. Jukes = 50 N
The 5th grade class pulls the rope with 150 N force
We need to find the net force on the rope. As two forces are acting in the opposite direction. The net force is given by :
F = 50 N - 150 N
= -100 N
Hence, the net force is 100 N.
