Take an arc of angle which make angle ‘θ’ with vertical. (dθ very small → point ‘P’)
⇒ Magnetic field due to infinite wire at this point
 (where r = R sinθ i.e. perpendicular distance of ‘P’ from line)
⇒ force dF on this Point (Arc of length dl = Rdθ) is 
Point (small arc) symmetric to point ‘P’ will also have same force dF
Force balancing on the arc having angle 2θ
Total force = 2 dF sinθ
Force on whole circular loop
