Question

Which objects can be electrically polarized?
A.negatively charged objects
B.positively charged objects
c.neutral objects
d.both positively and negatively charged objects

Answer 1

Polarization means to separate positive and negative charges through a distance by applying an electric field. On polarization two poles - one positive other negative gets developed. Every object is polarizable except perfect insulators which is an ideal case. It does not matter whether the object is neutral, positively charged or negatively charge. The only difference will be that a polarized neutral object will remain neutral after the process (since we are not removing any charges only displacing them) while a positively and negatively charged body will have an excess of charge over them.

Answer 2

In classical electromagnetism, polarization density (or electric polarization, or simply polarization) is the vector field that expresses the density of permanent or induced electric dipole moments in a dielectric material. When a dielectric is placed in an external electric field, its molecules gain electric dipole moment and the dielectric is said to be polarized. The electric dipole moment induced per unit volume of the dielectric material is called the electric polarization of the dielectric
