From a fixed point A, three normals are drawn to the parabola \(\scriptstyle\nabla^{2}\;=\;4\mathbf{a}\times\) at the points P, Q and R. Two circles C1 and C2 be drawn on AP and AQ as diameter. If slope of the common chord of the circles C1 and C2 be m1 and the slope of the tangent to the parabola at the point R be m2, then \(m_{1} \times m_{2}\) is equal to
- \(\frac{1}{2}\)
- 2
- \(-\frac{1}{2}\)
- - 2
Answer
