The electric intensity of infinite distance from the point charge is:
Correct answer: A. Zero
- A. Zero
- B. Infinite
- C. I-voltm-1
- D. Negative
Explanation
Electric field intensity = kq/r2 r = infinity E = K q / (infinity)2 E = 0 So the electric field intensity becomes zero at infinity.

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.
