5. In the adjoining figure, two circles with centres at
A and B, and of radii 5 cm and 3 cm touch each
other internally. If the perpendicular bisector of
AB meets the bigger circle in P and Q, find the
length of PQ.

Step-by-step explanation:

A and B are the centres of the circles with radii 5cm and 3cm respectively.

C is the mid-point of AB.

Extend AB upto O point on circumference of outer circle.

AB=AO−BO=5−3=2cm (since AO and BO are radii of larger and smaller circles)

AC=

=1cm

now in right angled triangle AMP

AC=1cm,AP=5cm
