The study of electric charges at rest in an electric field is:
Correct answer: B. Electrostatics
- A. Electromagnetism
- B. Electrostatics
- C. Quantum physics
- D. Magnetism
Explanation
Electrostatics is the branch of physics concerned with the study of stationary electric charges and the electric fields they create. It focuses on understanding the behavior of electric charges when they are at rest and the interactions between them. Topics in electrostatics include Coulomb's law, electric fields, electric potential, capacitance, and the behavior of conductors and insulators. Therefore, electrostatics is specifically dedicated to the study of electric charges at rest in an electric field.

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.
