An equilateral triangular frame is made ...

An equilateral triangular frame is made of three thin 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 `omega` 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

A

B

`(momega^2l)/2`

C

`sqrt(3momega^2l)/2`
