Please HELP!!! Mechanics, Statitics of a Particle watch

    • Thread Starter

    It's Q6 from Ex 4d in M1

    I'm stuck on...

    "Newton's Cradle consists of 5 small steel spheres, each suspended by 2 light strings. Modelling this be a number of particles each suspended by by 2 strings inclined at 80° to the horizontal, find the tension in each string when:

    a the steel sphere in 0.8N
    b the mass of each steel sphere is 0.1kg"

    No diagram was given with this question and I would appreciate if someone could also suggest the accompanying diagram with this question! I thought I had one but the calculations based off it were wrong...

    EDIT: the answers should be 0.406N and 0.498N

    So, help would be greatly appreciated! x
