Physics - Elecrostatics Question with Solution | TestHub

The peak electric field produced by the radiation coming from the$8 \mathrm{W}$bulb at a distance of$10 \mathrm{m}$is$\frac{x}{10}\sqrt{\frac{{\mu }_{0}c}{\pi } }\mathrm{V} {\mathrm{m}}^{-1}$. The efficiency of the bulb is$10\%$and it is a point source. The value of$x$is,
