A book with a mass of 8 kg is at rest on a horizontal surface of a table, as shown below. The magnitude of the normal force acting on the book is -
A.8
B.40
C.80
D.100

N = 80 N

Explanation:

Given that,

Mass of a book, m = 8 kg

We need to find the magnitude of the normal force acting on the book. Normal force acting on an object is balanced by its weight such that,

N = mg

g is the acceleration due to gravity

So, the correct option is (c) "80 N".

are there answer choices to this question? this seems like a question where you have options to choose from.

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary
