Bill is pushing a box with 10 N of force to the left, while Alice is pushing the box with 30 N of force to the right. What is the net force?

Fnet = 20 Newton

Explanation:

Let the force applied by Brian be Fb.

Let the force applied by Alice be Fa.

Given the following data;

Force, Fb = 10N

Force, Fa = 30N

To find the net force, Fnet;

Net force can be defined as the vector sum of all the forces acting on a body or an object i.e the sum of all forces acting simultaneously on a body or an object.

Mathematically, net force is given by the formula;

Where;

Since the two force applied to the box are acting in opposite direction, we would subtract their values to find the net force.

Fnet = Fa - Fb

Fnet = 30 - 10

Fnet = 20 Newton
