## Question

### Solution

Correct option is

0.011 cm

The wavelength of waves in the rod = 2l (l = length of rod). Since the vibrations are longitudinal,   Since V = Al (where A is the area of c.s.) If x is the increase in length produced by 10 kg weight, it follows:  from eq. (2) and (3), Solving, we get x = 0.011 cm.
