Given:
The strength of the magnetic field is B = 0.5 T
The velocity of the electron is
[tex]v=\text{ 4}\times10^6\text{ m/s}[/tex]The charge on an electron is
[tex]q=-1.6\times10^{-19}\text{ C}[/tex]To find the force.
Explanation:
The force can be calculated as
[tex]\begin{gathered} F=qvB \\ =1.6\times10^{-19}\times4\times10^6\times0.5 \\ =3.2\times10^{-13}\text{ N} \end{gathered}[/tex]
