8. As shown in the figure, the ACB is a smooth, long enough "A" shaped frame fixed in a vertical plane, where the angle between the CA and CB sides and the vertical direction are both O. P, Q are two light rings. The small rings are placed on the CA and CB respectively. Ends of the two strings OP and OQ are attached to the P and Q rings, and the other ends are tied together at node O. The hook of mass m is hung below node O. The lengths of the two strings of OP and OQ are 11 and 12. If 11:12=2:3, Find the ratio of the tension of the two ropes. с li 12 Q A В m
