Physics Question from JEE Main 2023 · 25 January, Shift 1

An object of mass 8 kg8 \, \text{kg} is hanging from one end of a uniform rod CD of mass 2 kg2 \, \text{kg} and length 1 m1 \, \text{m} pivoted at its end C on a vertical wall. It is supported by a cable AB such that the system is in equilibrium. The tension in the cable is: (Take g=10 m/s2g = 10 \, \text{m/s}^2)

A horizontal rod CD is pivoted at C on a vertical wall, with cable AB making 30 degree angle at point B, and an 8 kg mass hanging from end D. Distances shown are 60 cm from C to B and 40 cm from B to D.
