Vedclass · Answer

$\Rightarrow E =\overrightarrow{ E }=30 \hat{ j } \sin \left(1.5 	imes 10^{7} t -5 	imes 10^{-2} x ight) V / m$

$\Rightarrow B \Rightarrow E / V \Rightarrow \frac{30}{1.5 	imes 10^{7}} 	imes 5 	imes 10^{-2}$

$\Rightarrow 10^{-7}$ Tesla

$\Rightarrow F _{ mag }= q (\overrightarrow{ V } 	imes \overrightarrow{ B })=| q VB |$

$=1.6 	imes 10^{-19} 	imes 0.1 	imes 3 	imes 10^{8} 	imes 10^{-7}$

$=4.8 	imes 10^{-19} N$
