Answer:

P = 96 J

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

[tex]E=8\ N\times 12\ m\\E=96\ J[/tex]

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