A) \[1.96\times {{10}^{-4}}\,T\]
B) \[1.96\times {{10}^{-5}}\,T\]
C) \[1.96\times {{10}^{4}}\,T\]
D) \[1.96\times {{10}^{5}}\,T\]
Correct Answer: B
Solution :
[b] We know that \[\frac{B}{{{B}_{^{H}}}}=\tan \theta \] or \[B={{B}_{H}}=\tan \theta \] \[=0.34\times {{10}^{-4}}\tan \,30{}^\circ =1.96\times {{10}^{-5}}\,T\]You need to login to perform this action.
