A) \[{{T}_{h}}={{T}_{c}}\]
B) \[{{T}_{h}}=2{{T}_{c}}\]
C) \[{{T}_{h}}=1.5{{T}_{c}}\]
D) \[{{T}_{h}}={{0.5}_{c}}\]
Correct Answer: A
Solution :
\[\because \] \[T=2\pi \sqrt{\frac{1}{\mu B}}\] |
\[\frac{{{T}_{h}}}{{{T}_{c}}}=\sqrt{\frac{{{I}_{R}}}{{{I}_{c}}}\times \frac{{{\mu }_{c}}}{{{\mu }_{h}}}}\] |
\[=\sqrt{2\times \frac{1}{2}}=1\] |
\[{{T}_{h}}={{T}_{c}}\] |
