Q.

There are 2 circles say A, B. A has 20 units radius and B has 10 units radius and distance from centers of A and B is 40 units. Where will be the intersection point of external tangents?

A. to the left of two circles
B. to the right of the two circles
C. middle of the two circles
D. they intersect at midpoint of line joining the centers
Answer» B. to the right of the two circles
Explanation: a has 20 units radius and b has 10 units radius. so, the tangents go along the circles and meet at after the second circle that is b that is the right side of both circles. and we asked for external tangents so they meet away from the circles but not in between them.
