When a dielectric material placed in uniform electric field, which of the following option is NOT CORRECT :
Answer & explanation
Correct answer: option 2
The free movement of charges in a dielectric is not possible as electron is bounded with the nucleus.
The external field induces dipole moment by stretching molecules of dielectrics as it applies force on nucleus and electron in opposite direction.
The external field induces dipole moment by re-orienting molecules of dielectrics as it apply a torque which try to align the dipoles.
