(D) Energy density |
(II) $kg\, m^{-1} s^{-2}$ |
- Electric flux = Electric field $\times$ area $\to$ unit = $V/m \times m^2 = Vm \to$ (III)
- Polarisation = dipole moment per unit volume $\to$ unit = $C \cdot m/m^3 = C/m^2 \to$ (IV)
- Electric field = force/charge $\to$ unit = $N/C = V/m \to$ (I)
- Energy density = energy per unit volume $\to$ unit = $J/m^3 = kg \, m^{-1}s^{-2} \to$ (II)
