Problem

An electron is constrained to move along the

y

-axis with a speed of

0.1c

(

c

is the speed of light) in the presence of an electromagnetic wave, whose electric field is

\vec{E} = 30 \hat{j} \sin(1.5 \times 10^7 t - 5 \times 10^{-2} x)\ \text{V/m}

. The maximum magnetic force experienced by the electron will be: (given

c = 3 \times 10^8\ \text{m s}^{-1}

& electron charge =

1.6 \times 10^{-19}\ \text{C}

) a.

3.2 \times 10^{-18} \text{ N}

2.4 \times 10^{-18} \text{ N}

4.8 \times 10^{-19} \text{ N}

1.6 \times 10^{-19} \text{ N}
