Abook is on the table. if the weight of the book is 25 newtons, what is the magnitude and direction of the normal force? a. 2.5 newtons in the downward direction b. 2.5 newtons in the upward direction c. 25 newtons in the upward direction d. 25 newtons in the downward direction e. 25 newtons perpendicular to the gravitational force

Magnitude : 25 N

Direction: upward

Explanation:

The weight of the book is 25 N and is directed downward: this is the force exerted by the book on the table.

As stated in Newton's third law, for every object A that exerts a force on an object B, object B exerts an equal and opposite force on object A.

In this case, object A is the book and object B is the table. Based on Newton's third law, we can say that the table exerts an equal and opposite force on the book: therefore, the magnitude of the normal force is equal to the weight of the book (25 N), while the direction is opposite (so, upward).

the answer would be

C.  25 newtons in the upward direction

Explanation:

newtons law states that every action has an equal yet opposite reaction there for the book is 25n down so the opposite would be 25n in the upward direction.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
