A) \[1.679\times {{10}^{-5}}tesla\]
B) \[2.028\times {{10}^{-4}}tesla\]
C) \[1.257\times {{10}^{-3}}tesla\]
D) \[1.512\times {{10}^{-6}}tesla\]
Correct Answer: C
Solution :
\[B={{10}^{-7}}\frac{2\pi ni}{r}={{10}^{-7}}\times \frac{2\times \pi \times 25\times 4}{5\times {{10}^{-2}}}=1.257\times {{10}^{-3}}\,T\]
