The ratio: gravitational force/electrostatic force between two electrons is always:

Explanation

Option A : Gravitational force / electrostatic force is not greater than unity. Option: B Electrostatic forces are much stronger than gravitational forces. This is because gravity depends on mass, atoms have tiny masses so the gravitational force between them is close to zero. Whereas, the electrostatic force related to charges is bigger. The ratio of gravitational force to electrostatic force is always less than 1.
