Q. From a point ' $P$ ' three normals are drawn to the parabola $y^2=4 x$ such that two of them make angles with the abscissa axis, the product of whose tangents is 2 . Suppose the locus of the point ' $P$ ' is a part of a conic ' $C$ '. Now a circle $S =0$ is described on the chord of the conic ' $C$ ' as diameter passing through the point $(1,0)$ and with gradient unity. Suppose (a,b) are the coordinates of the centre of this circle. If $L_1$ and $L_2$ are the two asymptotes of the hyperbola with length of its transverse axis $2 a$ and conjugate axis $2 b$ (principal axes of the hyperbola along the coordinate axes) then answer the following questions. Locus of $P$ is a part of
