A) 64 cm/sec in ? x direction
B) 32 cm/sec in ? x direction
C) 32 cm/sec in + x direction
D) 64 cm/sec in + x direction
Correct Answer: D
Solution :
The given equation can be written as \[y=4\sin \,\left( 4\pi t-\frac{\pi x}{16} \right)\] Þ \[(v)=\frac{\text{Co-efficient of}\,t(\omega )}{\text{Co-efficient of}\,x(K)}\] Þ \[v=\frac{4\pi }{\pi /16}=64\,cm/sec\] along +x direction.You need to login to perform this action.
