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)

Question

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)

4.8 $ \times $ 10^–19 N

2.4 $ \times $ 10^–18 N

3.2 $ \times $ 10^–18 N

1.6 $ \times $ 10^–18 N
