A) \[3\sqrt{\frac{7}{2}}\]
B) \[\sqrt{14}\]
C) \[\sqrt{\frac{19}{2}}\]
D) \[\frac{3}{\sqrt{2}}\]
Correct Answer: A
Solution :
\[OQ=\frac{13}{\sqrt{26}}\] \[OR=\sqrt{38}\] \[\therefore QR=\sqrt{{{(OR)}^{2}}-{{(OQ)}^{2}}}\] \[=\sqrt{\frac{63}{2}}=3\sqrt{\frac{7}{2}}\]You need to login to perform this action.
