When the medium is an insulator, the electrostatic force between the charges is:
Correct answer: A. Decreased
- A. Decreased
- B. Zero
- C. Increased
- D. None of above
Explanation
When charges are in an insulating medium, such as glass or rubber, their ability to move freely is restricted. Insulators have high electrical resistance, meaning charges cannot flow easily. As a result, charges tend to stay localized, leading to a reduction in the overall electrostatic force between them compared to if they were in a conductor where charges could move more freely and interact more strongly.

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.
