A) \[6.28\times {{10}^{-4}}T\]
B) \[6.28\times {{10}^{-5}}T\]
C) \[3.14\times {{10}^{-4}}T\]
D) None
Correct Answer: A
Solution :
If the solenoid is of infinite length and the point taken is inside the solenoid then \[{{B}_{in}}={{\mu }_{0}}ni\,=4\pi \,\times {{10}^{-7}}\,\times \frac{100}{10\times {{10}^{-2}}}\]\[\times 0.5\,=6.28\,\times {{10}^{-4}}T\]You need to login to perform this action.
