A) \[2\pi \times {{10}^{-3}}T\]
B) \[2\pi \times {{10}^{-5}}T\]
C) \[4\pi \times {{10}^{-3}}T\]
D) \[4\pi \times {{10}^{-5}}T\]
Correct Answer: A
Solution :
(a) \[2\pi \times {{10}^{-3}}T\] \[B={{\mu }_{0}}nl=4\pi \times {{10}^{-7}}\times 5\times 1000=2\pi \times {{10}^{-3}}T.\]You need to login to perform this action.
