Question 43

A non uniform rod AB AB\,AB has length 200 cm and mass 15 kg. A mass of 10 kg is placed on the rod at CCC, where AC=40AC = 40AC=40 cm. The rod is held in horizontal equilibrium by two light inextensible strings attached at A A\,A and BBB.

Figure 1 shows a horizontal non-uniform rod AB with a 10 kg mass at C, where AB is 200 cm and AC is 40 cm.

Given that the distance of the rod's centre of mass from A A\,A is 120 cm, find the difference between the tensions in the strings at A A\,A and BBB.
