JEE Main 2022 Physics question
Given below two statements: One is labelled as Assertion (A) and other is labelled as Reason (R). Assertion [A]: Non-polar materials do not have any permanent dipole moment. Reason (R): When a non-polar material is placed in an electric field, the centre of the positive charge distribution of it's individual atom or molecule coincides with the centre of the negative charge distribution. In the light of above statements, choose the most appropriate Ans. from the options given below.
Answer: (3)
Solution
A non-polar material has no permanent dipole moment, so (A) is correct. When it is placed in an electric field, the positive and
