A)
B)
C)
D)
Correct Answer: B
Solution :
[b] \[I=\frac{\varepsilon }{R}=\frac{\left| d\phi \left. /dt \right| \right.}{R}=\frac{B.\frac{dA}{dt}}{R}\] \[=\frac{B\frac{d}{dt}\left( \frac{1}{2}h.b \right)}{R}\propto \frac{Bb\frac{dh}{dt}}{R}\propto Bbv\] \[\therefore \,\,\,\,b\propto t\Rightarrow I\propto t\]You need to login to perform this action.
