A) \[6.53\times {{10}^{-3}}\,ampere\]
B) \[13.25\times {{10}^{-10}}\,ampere\]
C) \[9.6\times {{10}^{6}}\,ampere\]
D) \[1.04\times {{10}^{-3}}\,ampere\]
Correct Answer: D
Solution :
\[B=\frac{{{\mu }_{0}}}{4\pi }.\frac{2\pi i}{r}\Rightarrow 12.56={{10}^{-7}}\times \frac{2\pi \times i}{5.2\times {{10}^{-11}}}\] \[\Rightarrow i=1.04\times {{10}^{-3}}\,A\]You need to login to perform this action.
