Step 1: Convert the density to charge using dq = ρ dV, dq = λ dl, or dq = σ dA as appropriate. Step 2: Integrate over the stated region and then use Coulomb's law/Gauss's law for the field or flux. Step 3: Apply the given radius/position limits and simplify. Final: Option B. In this specific setup, apply the calculation to: A semi-infinite charged wire with charge density +λ₁ is placed along the axis of a uniformly charged ring.
