A) 2.34 W
B) 3.84 W
C) 4.80 W
D) 5.78 W
Correct Answer: A
Solution :
Velocity, \[v=n\lambda \] \[v=150\times 0.06\] \[v=9\,m/s\] Power, \[P=2{{\pi }^{2}}{{n}^{2}}{{a}^{2}}(m/l)\,v\] \[=2\times {{(3.14)}^{2}}\times {{(150)}^{2}}\times {{(0.6)}^{2}}\times 0.2\times {{10}^{-3}}\times 9\] \[=2.87\,W\]You need to login to perform this action.
