A) 0.09 N
B) 0.36 N
C) 0.9 N
D) 3.6 N
Correct Answer: A
Solution :
[a] \[y=0.02\sin \,(x+30t)\] Comparing with standard equation \[y=A\sin (kx+\omega t),\,\,\omega =30,\,\,k=1\] Velocity of wave, \[v=\frac{\omega }{k}=\frac{30}{1}=30m/s\] Expression \[v=\sqrt{\frac{T}{m}}\]gives Tension \[T={{v}^{2}}n={{(30)}^{2}}\times {{10}^{-4}}=0.09\] NYou need to login to perform this action.
