Write the difference between the Coulomb force and the gravitational force between two electrons in a vacuum.

The Coulomb force between two electrons is an electrostatic force that is repulsive due to their like charges, described by Coulomb's law: F = k * (|q1 * q2|) / r², where k is Coulomb's constant, q1 and q2 are the charges, and r is the distance between them. The gravitational force between two electrons is an attractive force due to their mass, described by Newton's law of gravitation: F = G * (m1 * m2) / r², where G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers. Key differences: 1. Nature: Coulomb force is repulsive, gravitational force is attractive. 2. Magnitude: Coulomb force is much stronger than gravitational force at the scale of subatomic particles. 3. Dependence: Coulomb force depends on charge, gravitational force depends on mass.
