A circle has 2 inner circles touching internally through a chord of outer circle

Answer 1

Answer:

Ok we can see that but what is the question

Answer 2

Answer:

Given two cicrcles with centers C1 and C2 of radii 2 cm and 3 cm  touch internally .

the LONGEST chord AB of circle with center C2 must be a tangent to the circle with center C1.

from the figure, clearly the length of line segment C1C2 is 1 cm.

⟹AB=2×xfrompythagorastheorem,x=32−12=9−1=8=22⟹AB=2x⟹AB=2×22⟹AB=42

Ans: D
