Understanding Forces

* Force: A push or pull that can change an object's motion.

* Net Force: The overall force acting on an object, considering all forces and their directions.

Solving the Problem

1. Define Directions:

* Northward force = +10 N

* Southward force = -15 N (since it's in the opposite direction)

2. Calculate Net Force:

* Net force = Northward force + Southward force

* Net force = +10 N + (-15 N) = -5 N

Answer: The magnitude of the net force on the object is 5 N. Since the net force is negative, the object will experience a net force in the southward direction.
