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
Verified Correct Answer: B.
Physical Principles & Numerical Solution
v = \(\sqrt{\frac{T}{m}} = \sqrt{\frac{800}{0.08}} = 100\)m/s
