Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): Net dipole moment of a polar linear isotropic dielectric substance is not zero even in the absence of an external electric field.
Reason (R): In absence of an external electric field, the different permanent dipoles of a polar dielectric substance are oriented in random directions.
In the light of the above statements, choose the most appropriate answer from the options given below:
- A
(A) is correct but (R) is not correct
- B
Both (A) and (R) are correct but (R) is not the correct explanation of (A)
- C
Both (A) and (R) are correct and (R) is the correct explanation of (A)
- D
(A) is not correct but (R) is correct
