The tangents to having inclinations
and
intersect at
. If
,then the locus of
is
None of these.
Let the coordinates of be
. Let the equation of a tangent from
to the circle
be
Since, lies on
, therefore,
The is a quadratic in .Let the two roots be
and
, then
But and it s given that
.
. Hence, the locus of
is
.
Hence (C) is the correct answer.
