Question

A string of length 10.0 m and mass 1.25 kg is stretched with a tension of 50 N. If a transverse pulse is created at one end of the string, how long does it take to reach the other end? 

Solution

Correct option is

0.5 s

 

Tension T = 50 N, Length of the string (L) = 10.0 m. Mass of the string = 1.25 kg. Therefore, mass per unit length is   

                           

The speed of the pulse is 

                           

∴ Time taken by the pulse to reach the other end of the string is
