A square metallic loop of side `l` is placed near a fixed long wire carrying a current `i`(figure).The loop is moved towards right perpendicular to the wire with a speed `v` in the plane containing the wire and the loop.The `emf` induced in the loop when the rear end of the loop is at a distance `a=2l` from the wire is `(mu_(0)iv)/(xpi)`.Find out value of `x`.
