A) 1000
B) 3000
C) 10000
D) 5000
Correct Answer: D
Solution :
(d) 5000. We know that, \[B={{\mu }_{0}}nl\] \[\Rightarrow n\frac{B}{{{\mu }_{0}}l}=\frac{3.14\times {{10}^{-2}}}{4\pi \times {{10}^{-7}}\times 5}\]\[=\frac{3.14\times {{10}^{-2}}\times {{10}^{7}}}{4\times 3.14\times 5}=\frac{{{10}^{5}}}{20}=5000\]You need to login to perform this action.
