A) \[B\ell V\]
B) \[\frac{B{{\ell }^{2}}\omega }{2}\]
C) \[\frac{7B{{\ell }^{2}}\omega }{2}\]
D) \[\frac{5B{{\ell }^{2}}\omega }{2}\]
Correct Answer: C
Solution :
\[emf\,=B/{{V}_{average}}\,=Bl\left( \frac{{{V}_{1}}+{{V}_{2}}}{2} \right)\] \[=Bl\,\frac{7\omega l}{2}=\frac{7}{2}\,B{{l}^{2}}\omega \]You need to login to perform this action.
