The velocity v of the wave set-up by plucking a stretched string is found to depend on the tension T in the string, its length l and its mass m, and is given by v = kTx ly mz where x, y and z are unknown numbers and k is a constant. Find x, y and z.

The velocity v of the wave set-up by plucking a stretched string is found to depend on the tension T in the string, its length l and its mass m, and is given by v = kTx ly mz where x, y and z are unknown numbers and k is a constant. Find x, y and z.

  1. x = 1/2, y = 1/2 and z = – 1/2 ✓
  2. x = 1/2, y = 1/2 and z = 1/2
  3. x = 1/2, y = – 1/2 and z = – 1/2
  4. x = – 1/2, y = 1/2 and z = – 1/2
