A uniform magnetic field of 2.0 T exists perpendicular to the plane of two parallel conducting rails with separation of 50 cm and negligible resistance. Two resistors of resistances 
and 
are connected to the two rails (see figure). A conducting rod 
of resistance 
also connects the two rails and is made to slide on them with a uniform velocity of 
as shown. The current flowing in rod 
is
