A) \[1.96\times {{10}^{-4}}T\]
B) \[1.96\times {{10}^{4}}T\]
C) \[1.96\times {{10}^{-5}}T\]
D) \[~1.96\times {{10}^{5}}T\]
Correct Answer: C
Solution :
According to tangent law \[B=H\tan \theta \] \[B=0.34\times {{10}^{-4}}\tan {{30}^{o}}\] \[=0.34\times {{10}^{-4}}\times \frac{1}{\sqrt{3}}\] \[B=1.96\times {{10}^{-5}}T\]You need to login to perform this action.
