The total electric flux, leaving a spherical surface of radius 1 cm, and surrounding an electric dipole is:
Correct answer: B. Zero
- A. q/ε₀
- B. Zero
- C. 2q/ε₀
- D. 8πr² q/ε₀
Explanation
According to Gauss's Law, the total electric flux through a closed surface is proportional to the net charge enclosed. Since a dipole consists of equal positive (+q) and negative (- q) charges, the net enclosed charge is zero, making the total flux zero.

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.
