Two parallel long straight conductors lie on a smooth plane surface. Two other parallel conductors rest on them at right angle so as to form a square of side a. A uniform magnetic field B exists at right angle to the plane containing the conductors. Now, conductors starts moving outward witha constant velocity `v_0` at `t=0`. Then, induced current in the loop at any time is `(lamda` is resistance per unit length of the conductors)

A

`(aBv_(0))/(lambda(a+v_(0)l))`

B

`(aBv_(0))/(2lambda)`

C

`(Bv_(0))/(lambda)`

D
