Tension in a chain with circular motion

    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution

    What I know is tension is same in magnitude at all points of the chain along tangential direction due to the symmetry of the system.
    But how to find it out?

    Consider all the forces acting on a small piece of the chain, which subtends a differential angle.
    (What is the mass, acceleration, and acting forces on this piece?)
