The force that operates between charges called?

• A. Gravitational force
• B. Electrostatic force
• C. Magnetic force
• D. Nuclear force

Answer: (B)

The force that operates between electric charges is the electrostatic force. This is the electric interaction charges exert on each other, described by Coulomb’s law, F = k q1 q2 / r^2, and it can be attractive or repulsive depending on the charges. It’s a distinct kind of force from gravitational (between masses, always attractive), magnetic (from moving charges or magnets, related to magnetic fields), and nuclear forces (within the nucleus, very strong and short-range). Understanding electrostatic force explains why like charges repel and opposite charges attract, laying the groundwork for phenomena like static electricity and capacitor behavior.
