2 Fig. 2 shows a light string with an object of mass 4 kg attached at end A . The string passes over a smooth pulley and its other end B is attached to two light strings BC and BD of the same length. The strings BC and BD are attached to horizontal ground and are each inclined at \(20 ^ { \circ }\) to the vertical.
The system is in equilibrium.

- What information in the question tells you that the tension is the same throughout the string AB ?
- What is the tension in the string AB ?
- Calculate the tension in the strings BC and BD .
