A sonometer wire of linear density 0.08kg m-1 subjected to a tension of 800N is plucked. Calculate the speed of a pulse which moves from one end of the wire to the other
  • A.
    179.0ms-1
  • B.
    100.0ms-1
  • C.
    15.8ms-1
  • D.
    8.0ms-1
Correct Answer: Option B
Explanation

v = (sqrt{frac{T}{m}} = sqrt{frac{800}{0.08}} = 100)m/s
