The locus of points inside a circle and equidistant from two fixed points on the circumference of the circle.

Describe : The locus of points within a circle that are equidistant from the end points of a given chord.

The locus of the centres of all circles passing through two fixed points.

A point is selected at random from inside a circle. The probability that the point is closer to the circumference of the circle than to its centre, is

A point charge q is held at the centre of a circle of radius r. B,C are two points on the circumference of the circle and A is a point outsdie the circle . If W_("AB") charge q_(e ) from A to B and W_("AC") represents the workdone from A to C ,then

Statement-1: The locus of point z satisfying |(3z+i)/(2z+3+4i)|=3/2 is a straight line. Statement-2 : The locus of a point equidistant from two fixed points is a straight line representing the perpendicular bisector of the segment joining the given points.

Find the equation of the circle in which the chord joining the points (a,b) and (b, - a) subtends an angle of 45^@ at any point on the circumference of the circle.

The locus of the mid-points of the chords of the circle of lines radiùs r which subtend an angle pi/4 at any point on the circumference of the circle is a concentric circle with radius equal to (a) (r)/(2) (b) (2r)/(3) (c) (r )/(sqrt(2)) (d) (r )/(sqrt(3))

A wire of resistance 10 Omega is bent to form a circle. P and Q are points on the circumference of the circle dividing it into a quadrant and are connected to a Battery of 3 V and internal resistance 1 Omega as shown in the figure. The currents in the two parts of the circle are

The locus of a point equidistant from two points with position vectors veca and vecb is

The radii of two circles are 19 cm and 9 cm respectively. Find the radius of the circle which has circumference equal to the sum of the circumferences of the two circles.
