When a solid body is negatively charged by friction, it means that the body has
Correct answer: A. acquired excess of electrons
- A. acquired excess of electrons
- B. lost some protons
- C. acquired some electrons and lost a lesser number of protons
- D. lost some positive ions
Explanation
When a solid body is negatively charged by friction, it means that it has gained electrons from the material it rubbed against. Electrons are negatively charged particles. Therefore, the correct option is (a).Incorrect options: (b) Losing protons would result in a positive charge, not a negative one.(c) This option is partially correct as the body acquires electrons, but it does not lose protons.(d) Losing positive ions wouldn't result in a negative charge.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
