State Coulomb's Law.
Force between two charges: F = kq₁q₂/r² — where k = 9×10⁹ Nm²/C²
What is electric field?
Region around a charge where another charge experiences force — E = F/q — in N/C
What is electric flux?
Number of electric field lines passing through a surface — Φ = E·A·cosθ
State Gauss's Law.
Total electric flux through a closed surface equals charge enclosed divided by ε₀
What is electric potential?
Work done per unit positive charge brought from infinity to a point — V = W/q — in Volts
