The inward and outward electric flux from a closed surface is respectively 8 x 10^3units and 4 x 10^3 units, then the net charge inside the closed surface is:
Correct answer: B. B:-4 x 10^3 ε0
- A. A:+4 x 10^3 ε0
- B. B:-4 x 10^3 ε0
- C. C:0 ε0
- D. D:+8 x 10^3 ε0
Explanation
Flux2-flux1= q/epsilon notQ= (4×103 - 8×103) epsilon

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.
