Question

For electrons revolving in permitted circular orbits, the centripetal force is provided by

• A. Nuclear attractive force between the nucleons
• B. Electrostatic force of attraction between the electrons and the nucleus
• C. Gravitational force between electrons and protons in an atom
• D. Magnetic force between the charged particles

Answer 1

The correct option is B Electrostatic force of attraction between the electrons and the nucleus

Gravitational force is the least force and its magnitude is nearly ${10}^{-37}$ between any two electrons, while the electrostatic force is responsible for the centripetal acceleration of electrons around the nucleus
