A) \[12\pi \times {{10}^{-5}}T\]
B) \[24\pi \times {{10}^{-5}}T\]
C) \[12\pi \times {{10}^{-4}}T\]
D) \[48\pi \times {{10}^{-6}}T\]
Correct Answer: B
Solution :
(b) \[24\pi \times {{10}^{-5}}T\] \[B={{\mu }_{0}}nl\] \[=4\pi \times {{10}^{-7}}\times 200\times 3=24\pi \times {{10}^{-5}}T\]You need to login to perform this action.
