Dear student Please ask ony ine question in one thread. 2. Eqn of the chord AB of the circle : x² + y² = a². whose mid point is (h,k) is --- => h x + ky = h² + k² (1) ∠ AOB = 90° , D is the mid point (h,k) => AB = Sqrt ( a² + b²) = a . √2 , AD = (a/2) √2 = a/√2 => OD² = (1/4).2.a² => h² + k² = a²/2 => x² + y² = a²/2 ………………. Answer (2) If the chord passes through a fixed point ( x₁ , y₁ )., then h. x₁ + k y₁ = h² + k² Hence the locus of the point in this case is --- x.x₁ + y.y₁ = x² + y² =
