Question

The length of common chord of the ellipse (x-1)^2/9+(y-2)^2/4=1 and the circle (x-1)^2+y-2)^2=1

Answer 1

Step-by-step explanation:

Clearly centre of the ellipse and the circle coincide and radius of the circle is 1.

and length of semi-minor axis of the ellipse is 2.

Hence the given circle completely lie inside the ellipse, therefore will not be any common chord.
