A) \[\frac{Q}{M}\]
B) \[\frac{M}{Q}\]
C) \[\frac{Q}{2M}\]
D) \[\frac{M}{2Q}\]
Correct Answer: C
Solution :
\[M=iA=\frac{Q}{T}A=\frac{Q\omega }{2\pi }\times \pi {{R}^{2}}=\frac{Q\omega {{R}^{2}}}{2}\] |
\[L=I\omega =M{{R}^{2}}\omega \] |
\[\therefore \] \[\frac{M}{L}=\frac{Q\omega {{R}^{2}}/2}{M{{R}^{2}}\omega }=\frac{Q}{2M}.\] |
