A) 250 m T
B) 150 m T
C) 125 m T
D) 75 m T
Correct Answer: A
Solution :
\[\frac{{{B}_{center}}}{{{B}_{axis}}}={{\left( 1+\frac{{{x}^{2}}}{{{r}^{2}}} \right)}^{3/2}}\Rightarrow \frac{{{B}_{center}}}{54}={{\left( 1+{{\left( \frac{4}{3} \right)}^{2}} \right)}^{3/2}}=\frac{125}{27}\] \[{{B}_{center}}=250\mu T\]You need to login to perform this action.
