Which object has the most gravitational potential energy? a. an 8 kg book at a height of 3m b. an 5 kg book at a height of 3 m c. a 5 kg book at a height of 2 m d. a book at a height of 2 m

an 8 kg book at a height of 3m

Explanation:

Potential energy is the energy possessed by an object by virtue of its position.

m= mass of object = 200 kg

g = acceleration due to gravity =

h = height of an object  

1. an 8 kg book at a height of 3m

2. an 5 kg book at a height of 3 m

3. an 5 kg book at a height of 2 m

4. a book at a height of 2 m

Thus a 8 kg book at a height of 3 m has most potential energy.
