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 \[\mu C\] can be less than \[{{\mu }_{0}}\]. Reason \[500\sqrt{2}{{\mu }_{0}}\]is valid only for ideal gases.A) If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion,
B) If both Assertion and Reason are true but the Reason is not the correct explanation of the Assertion.
C) If Assertion is true but Reason is false.
D) If both Assertion and Reason are false.
Correct Answer: B
Solution :
\[\delta =(n-1)A\] can be less than \[({{n}_{1}}-1){{A}_{1}}=({{n}_{2}}-1){{A}_{2}}\] for those substances which contract on heating like for water from 0 to \[{{A}_{2}}\frac{({{n}_{1}}-1){{A}_{1}}}{({{n}_{2}}-1)}=\frac{(1.54-1)\times 4}{(1.72-1)}={{3}^{o}}\].
