Physics - EM Waves Question with Solution | TestHub

A radiation is emitted by$1000 \mathrm{W}$bulb and it generates an electric field and magnetic field at$P$, placed at a distance of$2 \mathrm{m}$. The efficiency of the bulb is$1.25\%$. The value of peak electric field at$P$is$x\times {10}^{-1} \mathrm{V} {\mathrm{m}}^{-1}$. Value of$x$is                (Rounded-off to the nearest integer) [Take${\epsilon }_0=8.85\times {10}^{-12} {\mathrm{C}}^2 {\mathrm{N}}^{-1} {\mathrm{m}}^{-2}, c=3\times {10}^6 \mathrm{m} {\mathrm{s}}^{-1}$]
