Arc of a Circle

If two arcs of a circle are congruent; then corresponding chords are equal

If two arcs of a circle (or of congruent circles) are congruent,then corresponding chords are equal.

If the length of an arc of a circle of radius a is equal to that of an arc of a circle of radius 2a, then the angle of the corresponding sector of the first circle is double the angle of the corresponding sector of the other circle. Is this statement false? Why?

Theorem:-1If two arcs of a circle are congruent; the corresponding chord are equal and Equal chords of a circle substends equal angles at the centre.

A wire A , bent in the shape of an arc of a circle , carrying current of 2 and having radius 2 cm and another wire B, also bent in the shape of arc of a circle , carrying a current of 3 A and having radius of 4 cm , are placed as shown in the figure . The ratio of the magnetic fields due to the wires A and B at the common centre O is :

A wire of length 'L' is bent in to an arc of a circle and found to subtentd and angle of 'theta' radians at the centre.If a current of 'I' is passed through it, the magnetic induction at the center of the circle is

Prove that the right bisector of a chord of a circle,bisects the corresponding arc or the circle.

Prove that the right bisector of a chord of a circle,bisects the corresponding arc or the circle.
