A non-polar dielectric material is placed in an external electric field. Choose the correct statement(s) from the following:

(A) There will be no change in the positions of positive and negative charges inside the dielectric.
(B) The positive charges of molecules will shift opposite to the direction of the electric field.
(C) The negative charges of molecules will shift in the direction of the electric field.
(D) The positive charges of the molecules will shift in the direction of the field and negative charges of the molecules will shift opposite to the field.

Choose the correct answer from the options given below:

(D) only

The correct answer is Option (1) → (D) only

For a non-polar dielectric placed in an external electric field:

• Molecules have no permanent dipole moment initially.

• Under the field, charges inside molecules get displaced slightly, creating induced dipoles.

• Positive charges shift in the direction of the electric field.

• Negative charges shift opposite to the electric field.

Thus, the correct statement is:

(D) The positive charges of the molecules will shift in the direction of the field and negative charges of the molecules will shift opposite to the field.
