The electric field between twoparallel plates placed in vacuum is ‘E’. If a slab of dielectric constant $$\sqrt{3}$$ is inserted in between the plates such that the normal to the boundary makes an angle $$45^\circ$$ with the lines of electric force in between the plates. Find the angle $$(\theta)$$ between the electric lines in the medium between the plates (vacuum) and dielectrié slab.

A

$$60^\circ$$

B

$$15^\circ$$

C

$$30^\circ$$

D

$$25^\circ$$
