    A body of mass 700g hangs from the end of a long wire fixed to a high tree. A horizontal string attached to the body pulls it until the wire is at 30 degrees to the vertical.Find the tensions in the both the string and the wire

    2. Relevant equations
    Sine rule

    3. The attempt at a solution
