Answer:
Fnet = 20 Newton
Explanation:
Let the force applied by Brian be Fb.
Let the force applied by Alice be Fa.
<u>Given the following data;</u>
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
