Q. A 8m long string of rubber, having density $1.5 \times 10^3\,kg/m^3$ and young's.modulus $5\times10^6\,N/m^2$ is suspended from the ceiling of a room. The increase in its length due to its own weight will be $(g=10m/s^2)$

Mechanical Properties of Solids

Solution:

$K = \frac{F/A}{( \Delta l / l)}$
