Text Solution
Verified by ExpertsThe correct answer is:
A
Let the equation of the ellipse is 
.....(i)
Let 
be the poles.
Now polar of 
w.r.t. the ellipse is given by 
.....(ii)
If it is a normal to the ellipse then it must be identical with 
.....(iii)
Hence comparing (ii) and (iii), we get
⇒ ⇒ 
and 
Squaring and adding we get, 
∴ ∴ Required locus of 
is 
.
