    Particle attached to strings on a disc mechanics :help:

    A particle of mass 0.2 kg is attached to the end C of two light inextensible strings Ac and BC both of length 1m. The other ends A and B are attached to opposite ends of a diameter of a smooth disc of radius 0.8 m which is free to rotate in a horizontal plane about its center. The disc rotates with angular speed 10 rad /s and P remains in contact with the disc.
    (a) Calculate the tension in each string. (b) Given that the strings will break if the tension exceeds 30N, calculate the maximum speed at which the disc can rotte without the strings breaking.

    I have no clue how to work out (a). Somebody help
