If a point charge q is placed at the centre of a cube, what is the flux linked with each face of cube?
Correct answer: D. Φ = 1/6ε₀ q
- A. Φ = 1/ε₀ q
- B. Φ = 3/ε₀ q
- C. Φ = 6/ε₀ q
- D. Φ = 1/6ε₀ q
Explanation
The total flux through the cube is q/ε₀, and it is evenly divided among the six faces due to symmetry.

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.

Separation between the plates of a parallel plate capacitor is 5 mm. This capacitor, having air as the dielectric medium between the plates, is charged to a potential difference 25 V using a battery. The battery is then disconnected and a dielectric slab of thickness 3 mm and dielectric constant K = 10 is placed between the plates, as shown. Potential difference between the plates after the dielectric slab has been introduced is:
