1 A small object of mass 5 kg is attached to one end of each of two identical parallel light elastic strings. The upper ends of both strings are attached to a horizontal ceiling.
The object hangs in equilibrium at R , with the extension of each string being 0.1 m , as shown in Fig. 1.

- Find the stiffness of each string.
One of the strings is now removed and the object initially falls downwards. The object does not return to R at any point in the subsequent motion.
- Suggest a reason why the object does not return to \(R\).
