For Linear Charge Density?

Depending on how the charge is distributed, we will either consider the volume charge density ρ = dq dV , the surface charge density σ = dq dA , or the linear charge density λ = dq d A , where V, A and A stand for volume, area and length respectively.

What is linear charge density and surface charge density?

Linear charge density: Linear charge density at a point on a linear line of charge is defined as the charge distributed per unit length. ... Surface charge density: Surface charge density at a point on a charged surface is defined as the charge distributed per unit area.

What is the correct expression for the linear charge density?

linear charge density: λ≡ charge per unit length (Figure 5.6. 1a); units are coulombs per meter (C/m) surface charge density: σ≡ charge per unit area (Figure 5.6.
