Jonny and Patty are pushing against a basketball. Both of them push against theball on opposite sides with a force of 20 N to keep the ball still. What is the net force?
A
400 N
B
24 N
C
0 N
D
40 N
Explanation: 

Detailed explanation-1: -When the forces acting on an object have equal strength and act in opposite directions, they are balanced. These forces cancel out one another, and the motion of the object they are acting on remains unchanged.

Detailed explanation-2: -If two individual forces are of equal magnitude and opposite direction, then the forces are said to be balanced. An object is said to be acted upon by an unbalanced force only when there is an individual force that is not being balanced by a force of equal magnitude and in the opposite direction.

Detailed explanation-3: -Answer and Explanation: Balanced forces lead to no net movement and are the basis of engineering statics. More involved than statics is dynamics which involves objects in motion. Application of an unbalanced force means that there is a net force on the object.

Detailed explanation-4: -The net force = 0. Balanced forces: Balanced forces are those that are opposite in direction and equal in size. Balanced forces are considered to be in a state of equilibrium. When forces are balanced there is no change in direction.
