Directions: In the following questions, a statement of Assertion [A] is followed by a statement of Reason (R). Mark the correct choice as: |
Assertion [A]: Magnetic moment is measured in joule/tesla or amp \[{{m}^{2}}\]. |
Reason (R): Joule/tesla is equivalent to amp \[{{m}^{2}}\]. |
A) Both Assertion [A] and Reason (R) are true and Reason (R) is the correct explanation of Assertion [A]
B) Both Assertion [A] and Reason (R) are true but Reason (R) is not the correct explanation of Assertion [A]
C) Assertion [A] is true but Reason (R) is false
D) Assertion [A] is false and Reason (R) is also false
Correct Answer: A
Solution :
[a] Magnetic moment \[=\frac{joule}{tesla}=\frac{W}{B}=\frac{W}{F/qv}=\frac{Wqv}{F}\] \[=\frac{[M{{L}^{2}}{{T}^{-2}}][AT][L{{T}^{-1}}]}{[ML{{T}^{-2}}]}\] \[[A{{L}^{2}}]=amp\,{{m}^{2}}\]You need to login to perform this action.
