Question

For a volume charge distribution, if the volume charge density is ρ and a small volume element is dV, what is the charge element dq?

विकल्प

• dq = ρ dV

• dq = ρ/dV

• dq = ρ dl

• dq = ρ dS

Answer 1

For a volume charge distribution, the charge element dq is related to the volume charge density ρ and the infinitesimal volume element dV by the relationship dq = ρ dV. This follows from the definition ρ = dq/dV.
