A) 0.34
B) 0.255
C) 0.085
D) All of these
Correct Answer: A
Solution :
\[P=\frac{-B\partial S}{\partial x}\] \[=-{{10}^{-2}}\,B\times 2\pi \,\cos \,\left( 2000\,\pi t\,+\frac{100\,\pi x}{17} \right)\,\times \frac{50}{17}\] maximum when \[\cos \left( \frac{100\,\pi x}{17} \right)\,=+1\] Use option in above equation to justify it.You need to login to perform this action.
