Problem

Four different strings are stretched between identical supports. The tension FTF_{T} and linear mass density μ\mu for each string are given in the table. String P: FT=90 N,  μ=0.010 kg/mF_{T}=90\,\text{N},\; \mu=0.010\,\text{kg/m} String Q: FT=60 N,  μ=0.005 kg/mF_{T}=60\,\text{N},\; \mu=0.005\,\text{kg/m} String R: FT=25 N,  μ=0.0025 kg/mF_{T}=25\,\text{N},\; \mu=0.0025\,\text{kg/m} String S: FT=40 N,  μ=0.008 kg/mF_{T}=40\,\text{N},\; \mu=0.008\,\text{kg/m} Rank the strings by the speed of transverse waves that can travel on them, from greatest to least. (a) P >> Q >> S >> R (b) Q >> R >> P >> S (c) R >> Q >> S >> P (d) S >> P >> R >> Q
