Question

Quizplus · Accepted Answer

The electric force between two protons is much stronger than the gravitational force between them. This is because the electric force between charged particles is proportional to the square of the charges and inversely proportional to the square of the distance between them, while the gravitational force between masses is proportional to the product of the masses and inversely proportional to the square of the distance between them. The charges of protons are much greater than their masses, which makes the electric force much stronger than the gravitational force at the same distance.
