Question 41 of 75 in this shift, Physics question 16 of 25, Section A.
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 :
- (1)Both (A) and (R) are correct and (R) is the correct explanation of (A)
- (2)Both (A) and (R) are correct but (R) is not the correct explanation of (A)
- (3)(A) is correct but (R) is not correct
- (4)(A) is not correct but (R) is correctOfficial answer
