Figure shows a uniform circular loop of radius ‘a’ having specific resistance `rho` placed in a uniform magnetic field
B perpendicular to plane of figure. A uniform rod of length 2a & resistance R moves with a velocity v as shown.
Find the current in the rod when it has moved a distance `a/2` from the centre of circular loop.
[Given `B=sqrt3,a=2,v=3,rho=9/(4pi), R=2sqrt3` all in SI units]
