Question

3. What is the potential energy of a 8 Newton book sitting on a shelf that is 12 meters high?​

Answer 1

P = 96 J

Step-by-step explanation:

Given that,

Weight of the book, W = mg = 8 N

It is placed at a height of 12 m

We need to find the potential energy of the book. The potential energy of an object is given by the formula as follows :

E = mgh

mg = Weight

`E=8\ N* 12\ m\\E=96\ J`

So, the potential energy of the book is 96 J.
