A) 0.34
B) 0.255
C) 0.085
D) All of these
Correct Answer: A
Solution :
\[p=\frac{-B\partial S}{\partial x}=-{{10}^{-2}}B\times 2\pi \cos (2000\pi t+\]\[\frac{1000\pi x}{17})\]\[\times \frac{50}{17}\]Maximum when\[\cos \left( \frac{1000\pi x}{17} \right)=+1\]You need to login to perform this action.
