Answer:
C.It is zero.
Explanation:
The net force is the sum of all of the forces exerted on an object.
Identifying Forces
Force is measured in newtons, which is shortened to N. Additionally, force will always have a direction, like 5N up or 3N to the left.
Sometimes force will be negative to represent direction. A force moving down or to the left might be negative because moving down or to the left on an axis moves towards negative numbers.
Net Force
As stated above, the net force is the sum of all of the forces acting on an object. For example, if one object is being moved 5N to the left and 4N to the right, the net force will be 1N to the left.
On the other hand, if the forces are balanced, like 5N on both the left and right, then the forces cancel out. This leaves a net force of 0.
