Question

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

• A. $\vec{ P }=\varepsilon_{0} \vec{ E }+\vec{ D }$
• B. $\vec{ P }=\vec{ D }+\vec{ E }$
• C. $\vec{ D }=\varepsilon_{0} \vec{ E }+\vec{ P }$
• 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
$\vec{D}=\varepsilon_{0} \vec{E}+\vec{P}$
