Question

Equations of the circle touching the circle x2 + y2 - 15x + 5y = 0 at (1, 2) and also passing through the point (0, 2) is (A) 13 (x2 + y2) - 13x - 61y + 70 = 0 (B) x2 + y2 + 2x - 0 (C) 13 (x2 + y2) - 13x - 61y + 9 = 0 (D) none of these

Correct answer is (a) 13 (x2 + y2) - 13x - 61y + 70 = 0

Q. Equations of the circle touching the circle $x^{2} + y^{2} - 15 x + 5 y = 0$ at $(1, 2)$ and also passing through the point $(0, 2)$ is

$13 (x^{2} + y 2) - 13 x - 61 y + 70 = 0$

$x^{2} + y^{2} + 2 x - 0$

13 $(x^{2} + y^{2}) - 13 x - 61 y + 9 = 0$

none of these

Correct answer is (a) $13 (x^{2} + y 2) - 13 x - 61 y + 70 = 0$

Q. Equations of the circle touching the circle x2+y2−15x+5y=0 at (1,2) and also passing through the point (0,2) is

13(x2+y2)−13x−61y+70=0

x2+y2+2x−0

13 (x2+y2)−13x−61y+9=0
