In an electromagnetic wave, the maximum value of the electric field is $100\mathrm{ }\mathrm{V }{\mathrm{m}}^{-1}$. The average intensity is [${\epsilon }_0=8.8\times {10}^{-12} {\mathrm{C}}^{-2} {\mathrm{N}}^{-1} {\mathrm{m}}^2$]

• Correct answer
  A

  $13.2 \mathrm{W} {\mathrm{m}}^{-2}$
• B

  $36.5 \mathrm{W }{\mathrm{m}}^{-2}$
• C

  $46.7 \mathrm{W }{\mathrm{m}}^{-2}$
• D

  $765 \mathrm{W }{\mathrm{m}}^{-2}$

Hence, the correct answer is option: 'A'.
