If E be the electric intensity of an electrostatic field, then the electrostatics energy density is proportional to:
Correct answer: B. E2
- A. E
- B. E2
- C. I/E2
- D. E3
Explanation
The electrostatic energy density is proportional to E^2, where E is the electric field intensity. This is because the energy density is proportional to the square of the electric field, which means that the energy density increases as the electric field intensity increases.

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.
