If the radius of the circumcircle of the triangle TPQ, where PQ is chord of contact corresponding to point T w.r.to circle x 2 + y 2 – 2x + 4y – 11 = 0, is 6 units, then minimum distance of T from the director circle of the given circle is
A
6
B
12
C
6 
D
12 – 
Text Solution
Verified by ExpertsThe correct answer is:
D
(x – 1) 2 + (y + 2) 2 = 16
(x – 1) 2 + (y + 2) 2 = 32
⇒ OS = 
∴ required distance TS = OT – SO = 12 –
