Question

A rope is being pulled with a force of $100N$ and $80N$ in opposite directions. The net force acting on the rope is

• A. $80N$
• B. $100N$
• C. $180N$
• D. $20N$

Answer 1

The correct option is D $20N$

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Since the direction of the forces are opposite, the net force on the rope is equal to the difference of the two forces acting on the rope.
Here, the net force is equal to $100N-80N$, which is $20N$ and the object moves along the direction of the $100N$ force.
