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.
