The electric charges attract and repel each other due to-
Correct Answer: A. Electrostatic force
Explanation: The interaction between electric charges is governed by the electrostatic force, also known as the Coulomb force. According to the fundamental principles of electromagnetism, charges of the same type (positive-positive or negative-negative) exert a repulsive force on one another, while opposite charges (positive-negative) exert an attractive force. This behavior is a primary characteristic of matter and is mediated by electric fields that surround charged particles. While other forces like gravity are strictly attractive and nuclear forces operate at subatomic distances, the electrostatic force is specifically responsible for the attraction and repulsion observed between macroscopic and microscopic electric charges.
