A metallic rod of mass m and resistance ...

A metallic rod of mass m and resistance R is sliding over the 2 conducting frictionless rails as shown in Fig. An infinitely long wire carries a current `I_(0)`. The distance of the rails from the wire are b and a respectively.

Find the value of current in the circuit if the rod slides with constant velocity `v_(0)`

A

`1/R{E-(mu_(0)I_(0)v_(0))/(2 pi) 1n|(b)/(a)|}`

B

`1/R{E+(mu_(0)I_(0)v_(0))/(2 pi) 1n|(b)/(a)|}`

C

`1/R{E-(mu_(0)I_(0)v_(0))/(pi) 1n|(b)/(a)|}`

D

None of these
