Question

In figure, there are two concentric circles with centre O. PRT and PQS are tangents to the inner circle from a point P lying on the outer circle. If PR = 5 cm, find the length of PS.

Solution

Radius from circle bisect the chord
So, PQ = $\frac{1}{2}$ $\times$ PS
$\Rightarrow$ 5 = $\frac{1}{2}$ PS
$\Rightarrow$ PS = 10 cm
