In a circle, PQ and RS are two diameters that are perpendicular to each other. Find the length of the chord PR.
A. $$\frac{{{\text{PQ}}}}{2}$$
B. $$\sqrt 2 {\text{PQ}}$$
C. $$2{\text{PQ}}$$
D. $$\frac{{{\text{PQ}}}}{{\sqrt 2 }}$$
Answer: Option D
Solution (By Examveda Team)
Let, PO = RO = 1
PQ = 2
PQ = $$\sqrt 2 \times \sqrt 2 $$
PQ = PR × $$\sqrt 2 $$
PR = $$\frac{{{\text{PQ}}}}{{\sqrt 2 }}$$
