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 $$\overrightarrow E = 30\widehat j\sin \left( {1.5 \times {{10}^7}t - 5 \times {{10}^{ - 2}}x} \right)$$ V/m. The maximum magnetic force experienced by the electron will be : (given c = 3 $\times$ 108 ms–1 and electron charge = 1.6 $\times$ 10–19 C)
