Answer 2

ANSWER → A circle of centre P is drawn,

Chord AB is drawn of length 13cm as shown in figure. Let Q is the point on AB in such a way that PQ ⊥ AB.

we know, the chord is bisected by a line passing through centre and perpendicular upon it. here,

chord AB is perpendicular upon PQ.

so, AQ=QB=2A

AB⇒AQ=QB= 213=6.5 cm

hence, length of QB=6.5 cm.

hope you it's useful...
