Hey buddy,
◆ Answer-
v = 3.16 m/s
● Explanation-
# Given-
m = 7 kg
l = 70 cm = 0.7 m
T = 100N
# Solution-
Mass per unit length of rod is
μ = m/l = 7/0.7 = 10 kg/m
Speed of transverse wave is given by -
v = √(T/μ)
v = √(100/10)
v = √10
v = 3.16 m/s
Speed of the transverse wave is 3.16 m/s.
Hope this is useful...
