Question

For a charge distribution with volume density ρ, the total charge Q equals

Accepted Answer

A. {'text': '∫∫∫ ρ dV', 'label': 'A'}

1. Volume charge density ρ has units C/m³.
2. Total charge is obtained by integrating ρ over the entire volume.
3. Q = ∫∫∫ ρ dV.
4. For a uniform distribution ρ × V; for varying ρ the full integral is needed.
