Direction for: In each of the following questions a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements mark the correct answer as
Assertion: Dielectric polarization means formation of positive and negative charges inside the dielectric. Reason: Free electrons are formed in this process.A) If both assertion and reason are true and reason is the correct explanation of assertion
B) If both assertion and reason are true but reason is not the correct explanation of assertion
C) If assertion is true but reason is false
D) If both assertion and reason are false
Correct Answer: C
Solution :
When an electric field is applied to the dielectric, each molecule of dielectric gets polarized i.e., centres of gravity of positive and negative charges get displaced from each other. On the left face, a net negative charge \[-{{q}_{i}}\] and on the right face, a positive charge \[+\,{{q}_{i}}\]appears. Thus, electric dipoles are produced inside. This is the dielectric polarization. Hence, option (c) is correct.
