A) \[1.2\,T\]
B) \[1.2\,\times {{10}^{-10}}T\]
C) \[0T\]
D) \[1.2\times {{10}^{-5}}T\]
Correct Answer: D
Solution :
Magnitude of magnetic field due to current \[B=\frac{{{\mu }_{0}}}{2\pi }\frac{i}{r}\] \[B={{10}^{-7}}\times \frac{2\times 90}{1.5}=1.2\times {{10}^{-5}}T\]You need to login to perform this action.
