If two forces act on an object with equal magnitude but opposite directions, the net force is

Explanation:
The main idea is that the net force is the vector sum of all forces acting on an object. When two forces have the same strength but point in opposite directions, they cancel each other out, giving a net force of zero. With no net force, there is no acceleration (F_net = m a), so the object's velocity doesn’t change. If it starts at rest, it stays at rest; if it’s already moving, it keeps moving at the same speed in the same direction. That’s why the situation results in zero net force.
