Question

Imagine a text book laying on a table. According to Newton’s third law, which correct free body diagram shows the force of the table on the text book?

Diagram a is a box with an arrow pointing down

Diagram b is a box with an arrow pointing up

Diagram c is a box with an arrow pointing up and an arrow pointing down and they are the same length

Diagram d is a box with an arrow pointing up and an arrow pointing down, but the arrow pointing down is longer than the arrow pointing up

Answer 1

Please help me someone

Answer 2

Diagram C, this is because the table and the textbook exert the same force on each other as per Newton's third law which states that when two bodies interact they apply forces to one another that are equal in magnitude and opposite in direction.
:) Hope this helps!
