S2- S1=0 is the equation of common chord, let distance of s2 - s1 = 0 from the centre of any one of the circles be x, which can be easily calculated, use pythagoras to find length of common chord

Sir orthogonal circles mein ye formula aasaan ho jaata hai kyouki vo common chord tangent ki chord of contact bhi ban jaati hai 👍
