An infinitely long straight wire carrying current I , one side opened rectangular loop and a conductor C with a sliding connector are located in the same plane , as shown in the figure. The connector has length l and resistance R . It slides of the right with a velocity v. The resistance of the conductor and the self inductance of the loop are negligible . The induced current in the loop , as function of separation r between the conductor and the straight wire is :

Options

A. `(mu_(0))/(4pi) (Ivl)/(Rr)`
B. `(mu_(0))/(pi) (I vl)/(Rr)`
C. `(2mu_(0))/(pi) (I vl)/(R r)`
D. `(mu_(0))/(2pi) ( I vl)/( Rr)`
