Question 1 Report
A transverse wave is applied to a string whose mass per unit length is 3 x 10-2kgm-1. If the string is under a tension 12N, the speed of the propagation of the wave is
Answer Details
The speed of propagation of a wave on a string is given by the formula:
v = √(T/μ),
where T is the tension in the string and μ is the mass per unit length of the string.
Substituting the given values, we get:
v = √(12 N / 3 × 10^(-2) kg/m)
v = √(4 × 10^2)
v = 20 m/s
Therefore, the speed of propagation of the wave is 20 m/s, which corresponds to option (B).
