Given : Length (l) = 7 m
Mass (M) = 0.035 kg and tension (T) = 60.5 N.
Therefore, mass of string per unit length (m)
Mass (M) = 0.035 kg and tension (T) = 60.5 N.
Therefore, mass of string per unit length (m)
speed of wave

To find the speed of a wave on the string, we can use the formula:
v = √(T/μ)
where:
v is the speed of the wave
T is the tension in the string
μ is the linear mass density of the string
Given:
Length of the string (L) = 7 m
Mass of the string (m) = 0.035 kg
Tension in the string (T) = 60.5 N
First, let's calculate the linear mass density (μ) of the string:
μ = m / L
μ = 0.035 kg / 7 m
μ = 0.005 kg/m
Now, substitute the values of T and μ into the formula to find the speed (v) of the wave:
v = √(60.5 N / 0.005 kg/m)
v = √(12100 m²/s² / kg/m)
v = √(12100 m²/s² * m/kg)
v = √(12100 m³/s²/kg)
v = √(12100 m/s²)
v ≈ 110 m/s
Therefore, the speed of the wave on the string is approximately 110 m/s, which corresponds to option C.
v = √(T/μ)
where:
v is the speed of the wave
T is the tension in the string
μ is the linear mass density of the string
Given:
Length of the string (L) = 7 m
Mass of the string (m) = 0.035 kg
Tension in the string (T) = 60.5 N
First, let's calculate the linear mass density (μ) of the string:
μ = m / L
μ = 0.035 kg / 7 m
μ = 0.005 kg/m
Now, substitute the values of T and μ into the formula to find the speed (v) of the wave:
v = √(60.5 N / 0.005 kg/m)
v = √(12100 m²/s² / kg/m)
v = √(12100 m²/s² * m/kg)
v = √(12100 m³/s²/kg)
v = √(12100 m/s²)
v ≈ 110 m/s
Therefore, the speed of the wave on the string is approximately 110 m/s, which corresponds to option C.

Actually velocity of wave =under root T/m where m=mass /length so put value under root 60.5/0.035*7=110
