A) \[{{I}_{3}}<{{I}_{2}}<{{I}_{1}}\]
B) \[{{I}_{1}}={{I}_{2}}={{I}_{3}}\]
C) \[{{I}_{2}}>{{I}_{1}}>{{I}_{3}}\]
D) \[{{I}_{3}}>{{I}_{1}}>{{I}_{2}}\]
Correct Answer: A
Solution :
The radius of gyration about PQ axis is more than that about QR axis and the radius of gyradon about QR axis is more than that about PR axis. ie, \[{{K}_{PQ}}>{{K}_{QR}}>{{K}_{PR}}\] So, \[{{I}_{1}}>{{I}_{2}}>{{I}_{3}}\]
