Vedclass · Answer

(A) When a dielectric is placed in an external electric field $E_0$,the molecules of the dielectric get polarized.This polarization creates an induced electric field $E_i$ inside the dielectric.The direction of this induced electric field $E_i$ is opposite to the direction of the external electric field $E_0$.The net electric field $E$ inside the dielectric is given by $E = E_0 - E_i$.Since $E_i > 0$,the net electric field $E$ inside the dielectric is always less than the external electric field $E_0$.
