Question

For a non-uniform charge distribution, how is charge density mathematically represented?

Options

• λ, σ, or ρ = constant

• λ, σ, or ρ = always zero

• λ, σ, or ρ = independent of location

• λ, σ, or ρ = function of position

Answer 1

In a non-uniform charge distribution, the charge density is not constant but varies with position. Mathematically, λ, σ, or ρ is represented as a function of position coordinates, reflecting the spatial variation in charge concentration.
