Let 
be a parabola with focus S. Let the tangents to the parabola 
make an angle of 
with the line 
touch the parabola 
at 
and 
. Then the value of 
for which 
and 
are collinear is:
A
8 only
B
2 only
C
only
D
any 
Text Solution
Verified by ExpertsThe correct answer is:
D
Lines making angle 
with 
have slope 
.
Which are perpendicular to each-other so, A, S, Bare collinear for all 
.
