In a cavendish experiment that first measured gravity, a 0.730 kg lead ball was placed 0.230 m away from a 158 kg lead ball. how much gravitational force did that create?

Explanation:

According to Newton's law of Gravitation, the force exerted between two bodies of masses and  and separated by a distance  is equal to the product of their masses and inversely proportional to the square of the distance:

Where:

is the gravitational constant, which was thanks to Cavendish experiment

Solving:

e/c, where e is its total energy
