A 5kg marble is balanced at the edge of a 1.5 m table. What is the gravitational potential energy of the marble?

E = 73.5 J

Explanation:

Given that,

Mass of a marble, m = 5 kg

It is placed at the edge of a 1.5 m table

We need of find the gravitational potential energy of the marble. It is given by the formula as follows :

E = mgh

E = 5 kg × 9.8 m/s² × 1.5 m

E = 73.5 J

So, the potential energy of the marble is 73.5 J.
