## Question

### Solution

Correct option is

2.21 m/s & 1 sec

(a) As the string has mass and it is suspended vertically, tension in it will be different at different points. For a point at a distance x from the free end, tension will be due to the weight of the string below it. So if M is the mass of string of length L, the mass of length x of the string will be (M/L)x.   Here x = 0.5 m (b) From part (a) it is clear that the tension and so the velocity of the wave is different at different points. So if at point x the wave travels a distancedx in time dt,    #### SIMILAR QUESTIONS
