The electric field at a point situated at a distance d from a straight charged conductor is:
Correct answer: D. Inversely proportional to d
- A. Proportional to d
- B. Inversely proportional to d2
- C. Independent of d
- D. Inversely proportional to d
Explanation
Inversely proportional to d Explanation: The electric field due to a long, straight charged conductor is inversely proportional to the distance from the conductor (E ∝ 1/d).

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.
