प्रस्तरतले लतातरुगुल्मा नो भवन्तु पिष्टाः।

(क) प्रस्तर तले (ख) प्रस्तरस्य तलम् (ग) प्रस्तरस्य तले

Answer 2

Answer:

In the above figure, the line that is drawn from the centre of the given circle to the tangent PQ is perpendicular to PQ.

And so, OP ⊥ PQ

Using Pythagoras theorem in triangle ΔOPQ we get,

OQ2 = OP2+PQ2

(12)2 = 52+PQ2

PQ2 = 144-25

PQ2 = 119

PQ = √119 cm

So, option D i.e. √119 cm is the length of PQ.
