Polarisation of light — UPSC IFoS 2025 Physics PYQ
Buy PYQ Solution Manual →A certain linear, homogeneous, isotropic, dielectric material has a relative permittivity, \varepsilon_{\text{r}} = 1\cdot 8. If potential \text{V} = -4000\text{y} volts in the material, then find :
(i) The electric flux density \text{D}, and
(ii) The polarisation \text{P}. Take vacuum permittivity \varepsilon_0 = 8\cdot 85 \times 10^{-12}\text{ farad/m}.
