Three long wires are placed in xy plane ...

Three long wires are placed in xy plane in a gravity free space. 'I' is the current flowing in each wire. The currents are constant in magnitude. Distance between each wire is 'd' and `lamda` is the mass per unit length of each wire. Wires 'A' and wire 'C' are fixed and wire 'B' is slightly displaced along 'z' axis. The period of oscillation of wire 'B' is

A

`(pid)/(i)sqrt((lamdapi)/(mu_(0)))`

B

`(2pid)/(i)sqrt((lamdapi)/(mu_(0)))`

C

`(pid)/(2i)sqrt((lamdapi)/(mu_(0)))`

D

`(4pid)/(i)sqrt((lamdapi)/(mu_(0)))`
