The perpendicular distance between the centre of a circle and the longest chord of that circle is ______.

0

Concept Used

The longest chord of circle is diameter.

Explanation

Let us take a circle with AB as diameter and O as its center.

Here, AB is the longest chord. This can also be understood by drawing multiples chords, every time diameter will come out to be the longest chord.

Now, as the diameter is the longest chord and it passes through center. So, perpendicular distance between center and longest chord will be 0.

Therefore, the perpendicular distance between the center of a circle and the longest chord of that circle is 0.
