Gauss law cannot be used to find which of the following quantity?
Correct answer: D. permittivity
- A. Electric field intensity
- B. Electric flux density
- C. Charge
- D. permittivity
Explanation
Gauss's law cannot be used to find permittivity (εo). The value of the permittivity of free space is a fundamental constant in electromagnetism, and it is not determined through Gauss's law.

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.
