A sonometer wire of linear density 0.08kgm‾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

B. 100.0ms‾¹

Explanation

v = √T/m

=√800/0.08 = 100m/s
