    Particle P, mass M attached to a fixed point O by a light inextensible string, length a moving in a vertical circle centre O radius a. P is at the highest point, p=2mg. No air resistance

    1. Find the speed at the highest point.
    2.Find T when OP makes the angle 60' with the downward vertical.

    Thanks for any help in advance.

    The radial component of the resultant force is the force required to move in a circle, and circular motion equation applies.

    Draw diagrams, label forces.

    For 2, you'll additionally need conservation of energy to find the velocity at the given point.

    Post working if you're still stuck.
