Question
The locus of the centre of the circle which passes through $(0, a)$ and $(0,-a)$ is(a) $x+y=0$(b) $x=y$(c) $\mathrm{y}=0$(d) $x=0$
Step 1
The points $(0, a)$ and $(0, -a)$ are on the circle, so the distance from the center to these points is the same (since they are both radii of the circle). Show more…

The locus of the centre of a circle which passes through the point $(0,0)$ and cuts off a length $2 b$ from the line $x$ $=c$, is (A) $y^{2}+2 c x=b^{2}+c^{2}$ (B) $x^{2}+c x=b^{2}+c^{2}$ (C) $y^{2}+2 c y=b^{2}+c^{2}$ (D) none of these
The locus of the mid-point of the chord of the circle $x^{2}$ $+y^{2}-2 x-2 y-2=0$ which makes an angle of $120^{\circ}$ at the centre is (A) $x^{2}+y^{2}-2 x-2 y+1=0$ (B) $x^{2}+y^{2}+x+y-1=0$ (C) $x^{2}+y^{2}-2 x-2 y-1=0$ (D) none of these
If a circle passes through the point $(a, b)$ and cuts the circle $x^{2}+y^{2}=4$ orthogonally, then the locus of its centre is (A) $2 a x+2 b y+\left(a^{2}+b^{2}+4\right)=0$ (B) $2 a x+2 b y-\left(a^{2}+b^{2}+4\right)=0$ (C) $2 a x-2 b y+\left(a^{2}+b^{2}+4\right)=0$ (D) $2 a x-2 b y-\left(a^{2}+b^{2}+4\right)=0$
