A wire carrying current I is tied between points P and Q and is in the shape of a circular arc of radius R due to a uniform magnetic field B (perpendicular to the plane of the paper, shown by xxx) in the vicinity of the wire. If the wire subtends an angle `2theta_(0)` at the centre of the circle (of which it forms an arc) then the tension in the wire is:

`(IBR)/( 2 sin theta_0)`

`(IBR_0) /( sin theta_0)`

`(IBR)/(sin theta_0)`

`IBR `
