, which subtend a right angle at the centre is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Let 
be the pole w.r.t. 
......(i)
Then equation of polar is 
.....(ii)
The equation of lines joining the origin to the points of intersection of (i) and (ii) is obtained by making homogeneous (i) with the help of (ii), then
⇒ ⇒
Since the lines are perpendicular, then coefficient of 
coefficient of 
or 
.
Hence required locus is
