1 45J 2 30 J 3 70J 4 20 J 8 An equilateral triangular frame is made of three thin 38 massless rods Three point masses of mass m each are fixed at vertices of the frame as shown The system is rotated with uniform angular speed o about a fixed axis passing through A and normal to the plane of triangular frame Neglect the effect of gravity The tension in rod connecting mass B and C is 0 1 mort 3 mo t 3 m 2 mo t 4 Zero 1 45 J an 2 30 J 3 70J 4 20 J adv fa fa m di fare courant cenfua feren ald ad reft sie fra de fucidad y free A B C 1 mort 3 mo t m 0 2 m moo 4 Zero
