A uniform bar XY of mass 5.0 kg and length 300 cm is suspended by two inextensible identical wires P and Q. P is attached 50 cm from the end X and Q to the centre of mass C of the bar, such that they are vertical. A mass of 10.0 kg is attached to the end X of the bar.
(i) Draw and label the diagram of the arrangement
(ii) Determine the distance from the centre of mass C where another mass of 10.0 kg should be hung on the bar to keep the bar horizontal and to make the tension in Q four times the tension in P. [g = 10ms- 2]?
