Two thin infinite parallel plates have uniform charge densities + σ and -σ. The electric field in the space between them is
Correct answer: D. zero
- A. σ/2εο
- B. σ/60
- C. σ/εο
- D. zero
Explanation
Between two infinite parallel plates with opposite charge densities, the electric fields due to each plate cancel each other out in the space between them. Therefore, the net electric field in the space between the plates is zero.Incorrect options: (a) and (c) These values represent the electric field between the plates of a capacitor, not between oppositely charged plates.(b) This value doesn't represent the electric field between oppositely charged plates.

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.
