An object of mass 8 kg hanging from one end of a uniform rod CD of mass 2 kg and length 1m pivoted at its end C on a vertical wall as shown in figure. It is supported by a cable AB such that the system is in equilibrium. The tension in the cable is: (Take g=10m/s2g = 10 m/s^2) [Diagram: A uniform rod CD pivoted at C, supported by cable AB. Mass of 8kg hangs from D. Cable AB makes a 30 degree angle with the rod. Lengths 60cm and 40cm are indicated for parts of the rod. Pivot C is on a wall.]
