A) \[2\pi \mu \,V\]
B) \[\pi \mu \,V\]
C) \[\frac{\pi }{2}\mu V\]
D) \[2\mu V\]
Correct Answer: B
Solution :
Magnetic flux \[\text{o}|=\,B.A\] \[=B.\pi {{r}^{2}}\] Induced emf, \[|e|=\frac{d\text{o }\!\!|\!\!\text{ }}{dt}=B\pi 2r\frac{dr}{dt}\] \[=0.025\times \pi \times 2\times 2\times {{10}^{-2}}\times 1\times {{10}^{-3}}\] \[=\pi \mu V\]You need to login to perform this action.
