Sound is simultaneously produced at the ends of the two strings of the same length, one of rubber and the other of steel. In which string will the sound reach the other end earlier and why?

Answer:

                Speed of sound in a string, \[\upsilon =\sqrt{\frac{\Upsilon }{\rho }}.\] As the value of \[\Upsilon /\rho \] is larger for steel than for rubber, so sound will reach the other end earlier in the case of steel string.
