Physics · Electrostatic Potential

For a linear isotropic dielectric, the polarisation vector is related to the electric field by \( \mathbf{P} = \varepsilon_0 \chi_e \mathbf{E} \). The electric susceptibility \( \chi_e \) is:

1. A
   measured in \( \text{C}\cdot\text{m}^{-2} \)
2. B
   a dimensionless quantity
3. C
   measured in \( \text{V}\cdot\text{m}^{-1} \)
4. D
   measured in \( \text{F}\cdot\text{m}^{-1} \)
