A) \[5\text{ }A{{m}^{2}}\]
B) \[10\text{ }A{{m}^{2}}\]
C) \[20\text{ }A{{m}^{2}}\]
D) \[40\text{ }A{{m}^{2}}\]
Correct Answer: A
Solution :
Magnetic moment, \[M=niA\] \[M=100\times 3.2\times (\pi r_{1}^{2})\] \[=100\times 3.2\times \frac{22}{7}\times \frac{10}{100}\times \frac{10}{100}\] \[=10.048\,A-{{m}^{2}}\]You need to login to perform this action.
