railway RRB JE (CBT I + CBT II) Mock Test 2024 Electromagnetic Theory Electrostatics Electric Field in Material
The electric field between two parallel plates placed in a 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° with the lines of electric force in between the plates. Find the angle (θ) between the electric lines in the medium between the plates (vacuum) and dielectric slab
