What is the gravitational potential energy of a book with a mass of 0.30 kg on a 1.0 m high desk?

Potential energy, PE = 2.94 joules

Explanation:

Given that,

Mass, m = 0.3 kg

It is placed at a height of, h = 1 m

We need to find the gravitational potential energy of the book. It is given by :

PE = mgh

PE = 2.94 Joules

So, the potential energy of the book at this height is 2.94 Joules. Hence, this is the required solution.
