• A. $\vec{P}={\epsilon }_0\vec{E}+\vec{D}$
• B. $\vec{P}=\vec{D}+\vec{E}$
• C. $\vec{D}={\epsilon }_0\vec{E}+\vec{P}$
• D. $\vec{E}=\vec{D}+\vec{P}$

Answer 1

Answer: (C)

The relation between electric field vector $\vec{E}$, the displacement vector $\vec{D}$ and the polarization vector $\vec{P}$ for a dielectric placed in electric field $\vec{E}$ is given by
$\vec{D}={\epsilon }_0\vec{E}+\vec{P}$
