   Q3

   A metal rod of length $L$ rotates about one end at origin with a uniform angular velocity . The magnetic field radially falls off as $B(r)=B_o{e}^{-\lambda r};\lambda$ being a positive constant. The emf induced (neglecting the centripetal force on electrons in the rod) is :

   • A$B_o\omega \left[\frac{1}{{\lambda }^2}-e^{-\lambda L}\left(\frac{1}{{\lambda }^2}+\frac{L}{\lambda }\right)\right]$
   • B$B_o\omega \left[\frac{1}{{\lambda }^2}+e^{-\lambda L}\left(\frac{1}{{\lambda }^2}+\frac{L}{\lambda }\right)\right]$
   • C$B_o\omega \left[\frac{4}{{\lambda }^2}-e^{-2\lambda L}\left(\frac{1}{{\lambda }^2}+\frac{2L}{\lambda }\right)\right]$
   • D$B_0\omega \left[\frac{3}{{\lambda }^2}-e^{-3\lambda L}\left(\frac{3}{{\lambda }^2}+\frac{L}{\lambda }\right)\right]$
