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 answer from the options given below.
Both (A) and (R) are correct and (R) is the correct explanation of (A).
Both (A) and (R) are correct and (R) is not the correct explanation of (A).
(A) is correct but (R) is not correct.
(A) is not correct but (R) is correct.
Answers (1)
In the absence of electric field ,the centre of the positive charge distribution of it's individual atom or molecule coincides with the centre of negative chatge distribution
Therefore it has dipole moment only in the presence of electric field.
The correct option is (3)
