| ASSERTION: Magnetic moment is measured in Joule/tesla or amp \[{{m}^{2}}\]. |
| REASON: Joule/tesla is equivalent to amp\[{{m}^{2}}\]. |
A) If both assertion and reason are true and reason is the correct explanation of assertion.
B) If both assertion and reason are true and reason is not the correct explanation of assertion.
C) If assertion is true but reason is false.
D) If both assertion and reason are false.
E) If assertion is false but reason is true.
Correct Answer: A
Solution :
Magnetic moment \[=\frac{Joule}{Tesla}=\frac{W}{B}=\frac{W}{F/qv}\] \[=\frac{{{W}_{qv}}}{F}=\frac{\left[ M{{L}^{2}}{{T}^{-2}} \right]\left[ AT \right]\left[ L{{T}^{-1}} \right]}{\left[ ML{{T}^{-2}} \right]}\] \[=\left[ A{{L}^{-2}} \right]=amp\,\,{{m}^{2}}\]
