Answer
The volleyball should exert the same 20 N on Ana.
Explanation
The 3rd Newton's law of motion states that, for any action, there is an equal and opposite force.
This means a body placed on top of a table exerts a force, say X N, on the table. For the table to hold that body it must be exerting an equal force (X N) to the body.
∴ If Ana exerts a force of 20 N on the volleyball, the volleyball should exert the same 20 N on Ana.
The force exerted by the volleyball on Ana will be of [tex]\boxed{20\text{ N}}[/tex] but it will act in the opposite direction of the force applied by Ana on the volleyball.
Explanation:
According the the Newton's third law of motion, each and every action performed by one body on the other has equal and opposite reaction on the body in the opposite direction.
The magnitude of the reaction force by the second body on the first body is same as the magnitude of the action but the direction of the reaction force is opposite of the action force.
Write the expression for the force exerted by the volleyball on Ana.
[tex]\boxed{F_{V\rightarrow A}=-F_{A\rightarrow V}}[/tex]
The above expression shows that the reaction force of the volleyball on Ana will be same in magnitude as of the action applied by Ana but the direction of the reaction force will be opposite.
Thus, The force exerted by the volleyball on Ana will be of [tex]\boxed{20\text{ N}}[/tex] but it will act in the opposite direction of the force applied by Ana on the volleyball.
