Question

For a uniform charge distribution, what is the mathematical representation of charge density?

Options

• λ, σ, or ρ = exponentially decreasing

• λ, σ, or ρ = function of position

• λ, σ, or ρ = constant

• λ, σ, or ρ = zero everywhere

Answer 1

In a uniform charge distribution, the charge density is constant, meaning λ, σ, or ρ = constant throughout the distribution. This simplifies calculations as the density does not vary from point to point.
