Two thin infinite parallel plates have uniform charge densities + σ and -σ The electric field in the space between them is
Correct answer: D. σ/ εo
- A. σ/2 εo
- B. σ
- C. zero
- D. σ/ εo
Explanation
The electric field E1 due to the positive charge density (+σ) points away from that plate. And is equal to E1= σ/2 εoThe electric field E2 due to the positive charge density (-σ) points towards that plate the plate. And is equal toE2= σ/2 εoSo, both the electric fields are along one another.

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.
