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

Respuesta :

Answer:

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

[tex]N=8\ kg\times 10\ m/s^2\\\\N=80\ N[/tex]

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