A conductor wire carrying current `i` is placed symmetrically and parallel to a long conducting sheet having a current per unit width `j_(0)` and width d, as shown in the figure. The force per unit length on the conductor wire will be

A

`(mu_(0)j_(0)i)/(pi) tan^(-1)((d)/(2h))(-hatk)`

B

`(mu_(0)j_(0)i)/(pi)((2h)/(d))(-hatk)`

C

`(j_(0)i)/(mu_(0)pi)tan^(-1)((2h)/(d))(-hatk)`

D

`(j_(0)i)/(mu_(0)pi)tan^(-1)((d)/(2h))(-hatk)`
