• # question_answer In an electromagnetic wave, the electric and magnetising fields are $100\text{ }V/m$ and$0.265\text{ }A/m$. The maximum energy flow will be: A)  $76.5\,W/{{m}^{2}}$        B)  $46.7\,W/{{m}^{2}}$C)  $36.5\,W/{{m}^{2}}$        D)  $26.5\,W/{{m}^{2}}$

Amplitude of an electric field, ${{E}_{0}}=100\,V/m$ Amplitude of magnetising field, ${{H}_{0}}=0.265A/M$ $\therefore$    Maximum energy flow is given by             $E={{E}_{0}}\times {{H}_{0}}$                 $=100\times 0.265=26.5W/{{m}^{2}}$
