A point source of electromagnetic radiation has an average power output of \( 800 \mathrm{~W} \). The maximum value
\( \mathrm{P} \)
of electric field at a distance \( 4.0 \mathrm{~m} \) from the source is
(1) \( 64.7 \mathrm{~V} / \mathrm{m} \)
(2) \( 57.8 \mathrm{~V} / \mathrm{m} \)
W
(3) \( 56.72 \mathrm{~V} / \mathrm{m} \)
(4) \( 54.77 \mathrm{~V} / \mathrm{m} \)
