A) 0.02 m
B) 0.04 m
C) Zero
D) 0.028 m
Correct Answer: B
Solution :
\[\because \,\,\,k\,\,=\,\,\frac{\omega }{v}\] \[\omega \,\,=\,\,600\pi \,\,=\,\,2\pi x\,\] \[y=0.04\text{ }sin\text{ }\left( \omega t-kx \right)\] \[y=0.04\text{ }sin\text{ }\left( \omega t-\frac{\omega x}{v} \right)\] \[y=0.04\text{ }sin\text{ }\omega \,(t-\frac{x}{v})\] \[y=0.04\text{ }sin\text{ }600\pi \,(\frac{1}{100}-\frac{75}{100\,\,\times \,\,300})\] \[y=0.04\text{ }sin\text{ }\pi \left( \frac{225}{300} \right)\,\,=\,\,0.04\,m\]You need to login to perform this action.
