Physics - EM Waves Question with Solution | TestHub

An electron is constrained to move along the$y$-axis with a speed of$0.1 c$(c is the speed of light) in the presence of electromagnetic wave, whose electric field is$\overrightarrow{\mathrm{E}}=30\hat{\mathrm{j}}\sin \left(1.5\times {10}^7\mathrm{t}-5\times {10}^{-2}\mathrm{x}\right) \mathrm{V} {\mathrm{m}}^{-1}.$where$t$in in seconds and$x$is im meters.The maximum magnetic force experienced by the electron will be: (given$\mathrm{c}=3\times {10}^8 \mathrm{m} {\mathrm{s}}^{-1}$and electron charge$=1.6\times {10}^{-19} \mathrm{Coloumbs}$
