Questions
The tangents drawn from the origin to the circle are perpendicular if
detailed solution
Correct option is C
Equation of the given circle can be written as (x−p)2+(y−q)2=p2 (i)This has (p, q) as the centre and p as the radius showing that it touches y-axis. So one of the tangents from the origin to the circle is y-axis.⇒ Other tangent from the origin to the circle must be x-axis. which is possible if q = ± p.⇒ p2−q2=0.Talk to our academic expert!
