Here: Intensity of electric field E0=100 V text/m Intensity of magnetizing field H0=0.265 A text/m The maximum energy flow S=E0× H0=100× 0.265 =26.5 W text/m2

Q. In an electromagnetic wave, the electric and magnetizing fields are 100 V/m and 0.265 A/m. The maximum energy flow is:

$76.5 W / m^{2}$

$46.7 W / m^{2}$

$36.5 W / m^{2}$

$26.5 W / m^{2}$

Here: Intensity of electric field $E_{0} = 100 V / m$ Intensity of magnetizing field $H_{0} = 0.265 A / m$ The maximum energy flow $S = E_{0} \times H_{0} = 100 \times 0.265$ $= 26.5 W / m^{2}$

Q. In an electromagnetic wave, the electric and magnetizing fields are 100 V/m and 0.265 A/m. The maximum energy flow is:

76.5W/m2

46.7W/m2

36.5W/m2

26.5W/m2

Here: Intensity of electric field E0​=100V/m Intensity of magnetizing field H0​=0.265A/m The maximum energy flow S=E0​×H0​=100×0.265 =26.5W/m2

$76.5 W / m^{2}$

$46.7 W / m^{2}$

$36.5 W / m^{2}$

$26.5 W / m^{2}$

Here: Intensity of electric field $E_{0} = 100 V / m$ Intensity of magnetizing field $H_{0} = 0.265 A / m$ The maximum energy flow $S = E_{0} \times H_{0} = 100 \times 0.265$ $= 26.5 W / m^{2}$
