Q. Which among the following provides the centripetal force to an electron circulating around the nucleus?
Answer: electrostatic force of attraction
Notes: The correct answer is "electrostatic force of attraction." In an atom, electrons are negatively charged and are attracted to the positively charged nucleus due to Coulomb's law. This attraction provides the necessary centripetal force to keep the electron in a stable orbit around the nucleus. The balance between this electrostatic force and the electron's inertia allows for stable atomic structures.
