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