A) \[0.63\times {{10}^{-2}}T\]
B) \[1.26\times {{10}^{-2}}T\]
C) \[2.51\times {{10}^{-2}}T\]
D) 6.3 T
Correct Answer: B
Solution :
The magnetic field is given by \[B={{\mu }_{0}}ni\] where \[{{\mu }_{0}}=4\pi \times {{10}^{-7}}T\,m{{A}^{-1}},\] \[n=\frac{1000}{50\times {{10}^{-2}}},i=5A\] \[\therefore \] \[B=4\pi ={{10}^{-7}}\times \frac{1000}{50\times {{10}^{-2}}}\times 5\] \[B=1.26\times {{10}^{-2}}T\]You need to login to perform this action.
