1. Understand the Forces

* Applied Force: Two forces of 100 N each are pushing in the same direction. This gives a total applied force of 100 N + 100 N = 200 N.

* Friction Force: This opposes the motion and is 80 N.

2. Calculate the Net Force

The net force is the difference between the forces acting in opposite directions:

* Net Force = Applied Force - Friction Force

* Net Force = 200 N - 80 N

* Net Force = 120 N

Therefore, the net force acting on the object is 120 N.
