Question

Two protons are near each other with a separation of r. the protons have both an electrostatic and gravitational force acting between them. how does the electrostatic force compare to the gravitational force between the two particles?

Answer 1

The electrostatic force between two protons is significantly stronger than the gravitational force between them. This is because the gravitational force is comparatively weak for small masses such as protons, while electrostatic forces dominate at the atomic scale.

Step-by-step explanation:

When comparing the electrostatic force to the gravitational force between two protons, it's clear that there are substantial differences in their magnitudes. The electrostatic force between two charges is described by Coulomb's law and is proportional to the product of the charges divided by the square of the separation between them. Conversely, the gravitational force, as described by Newton's law of universal gravitation, is proportional to the product of the masses and inversely proportional to the square of the separation.

For protons, the electrostatic force is vastly stronger than the gravitational force. This is because the gravitational force is much weaker for objects with small masses, such as subatomic particles. The electrostatic force dominates within the atomic scale, leading to the conclusion that for two protons, the electrostatic interaction is overwhelmingly more significant than the gravitational interaction.
