P(3,2)" is a point on the circle "`x^(2)+y^(2)=13`" .Two points "A" ,"B" are on the circle such that `PA=PB=sqrt(5)` .The equation of chord "AB" is

B and C are points on the circle x^(2)+y^(2)=a^(2) A point A(b,c) lies on that circle such that AB=AC=d, the equation to BC is

If the line ax+by+11=0 meets the circle x^(2)+y^(2)=61 at A,B and P(-5,6) is on the circle such that PA=PB=10 then |a+b|=

From the point A(0,3) on the circle x^(2)+4x+(y-3)^(2)=0 a chord AB is drawn to a point such that AM=2AB. The equation of the locus of M is :-

From a point A(1, 1) on the circle x^(2)+y^(2)-4x-4y+6=0 two equal chords AB and AC of length 2 units are drawn. The equation of chord BC, is

AB is a chord of the circle x^(2)+y^(2)=(25)/(2).P is a point such that PA=4,PB=3. If AB=5 , then distance of P from origin can be:

A variable chord of the circle x^(2)+y^(2)=4 is drawn from the point P(3,5) meting the circle at the point A and B. A point Q is taken on the chord such that 2PQ=PA+PB The locus of Q is x^(2)+y^(2)+3x+4y=0x^(2)+y^(2)=36x^(2)+y^(2)=16x^(2)+y^(2)-3x-5y=0

Suppose A,B are two points on 2x-y+3=0 and P(1,2) is such that PA=PB. Then the mid point of AB is
