Formula Sheet — Electric Charges and Fields

Important formulas and equations from Electric Charges and Fields for AP EAPCET Physics.

Formulas — Electric Charges and Fields

Basic Properties of Electric Charge

Q = ±ne

Coulomb's Law

F = k|q₁q₂|/r²
F = (1/4πε₀)|q₁q₂|/r²
F⃗₁ = (1/4πε₀) Σᵢ (q₁qᵢ/r₁ᵢ²)r̂₁ᵢ

Electric Field

E⃗ = F⃗/q₀
E = kq/r²
E⃗ = (1/4πε₀) Σᵢ (qᵢ/rᵢ²)r̂ᵢ

Electric Flux and Gauss's Law

Φ = E⃗·A⃗ = EA cos θ
Φ = ∮E⃗·dA⃗
∮E⃗·dA⃗ = Q_enclosed/ε₀
