A wire carrying current I is tied between points P and Q and is in the shape of a circular arch of radius R due to a uniform magnetic field $\displaystyle B$ (perpendicular to the plane of the paper, shown by xxx) in the vicinity of the wire. If the wire subtends an angle $\displaystyle 2 \theta_0$ at the centre of the circle (of which it forms an arch) then the tension in the wire is :
