Question

A television of mass 13 kg sits on a shelf. What is the normal force acting on the television?

Answer 1

$13 \times 9.8 = 127.4$
B is the correct answer

Answer 2

Answer:

Normal force, F = 127 N

Explanation:

It is given that,

Mass of the television, m = 13 kg

It is sitting on the shelf. We have to find the normal force acting on it. The forces acting on it are normal force and its weight. So, the normal force is given by :

F = mg

g = acceleration due to gravity

$N=13\ kg\times 9.8\ m/s^2$

F = 127.4 Newton

or

F = 127 N

Hence, the normal force acting on the television is 127 N
