A string of length and mass per unit l...

A string of length and mass per unit length is used in atwood machine as shown in the figure. Masses of blocks are large in comparison with the mass of string. The transverse wave velocity in the string is:

A

`sqrt((4 mg)/(mu))`

B

`sqrt((4 mg)/(5 mu))`

C

`sqrt((4 mg)/(3 mu))`

D

`sqrt((4 mg)/(mu))`

Text Solution

Verified by Experts

The correct Answer is:
C
`T = (2(2m) (m)g)/(2m + m)`
`T = (4m^(2) g)/(3m)`, `T = (4mg)/(3)`
`v = sqrt((T)/(mu))` , `v = sqrt((4 mg)/(3 mu))`
