Two plates are 2cm apart, a potential difference of 10 volt is applied between them, the electric field between the plates is:
Correct answer: B. 500N/C
- A. 20 N/C
- B. 500N/C
- C. 5 N/C
- D. 250 N/C
Explanation
Electric Field (E)=Potential Difference (V)/Distance between the Plates (d) Given: Potential Difference (V) = 10 volts Distance between the Plates (d)=2 cm =0.02 meters Now, let's calculate the electric field (E)=10 volts/ 0.02 meters=500 N/C The correct option is: b) 500N

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.
