If two points P & Q on the hyperbola x 2 /a 2 − y 2 /b 2 = 1 whose centre is C be such that CP is perpendicular to CQ & a < b, then 
where λ is :
Text Solution
Verified by ExpertsThe correct answer is:
1
(1)
Sol.
CP ≡ = 
= 
r 1 where CP = r 1
∴ P(r 1 cos θ , r 1 sin θ )
Similarly 
Q (–r 2 sin θ , r 2 cos θ )
P & Q lies on Hyperbola
∴ 
∴ 
& 
∴ 
+ 
= 
= 
–
