A) \[26.5\text{ }W/{{m}^{2}}\]
B) \[36.5\text{ }W/{{m}^{2}}\]
C) \[46.7\text{ }W/{{m}^{2}}\]
D) \[765\text{ }W/{{m}^{2}}\]
Correct Answer: A
Solution :
[a] Here, amplitude of electric field, \[{{E}_{0}}=100\,V/m\] amplitude of magnetic field, \[{{H}_{0}}=0.265\,A/m\]. We know that the maximum rate of energy flow, \[S={{E}_{0}}\times {{H}_{0}}=100\times 0.265=26.5\,W/{{m}^{2}}\].
