Answer:Force is doubled
Explanation:
Given
Speed of Electron is doubled then
According to Lorentz theory Force experienced by Charge particle in a magnetic field
[tex]F_L=q(v\times B)[/tex]
where q=charge on particle
v=velocity of particle
B=magnetic Field
Supposing Magnetic Field is Perpendicular to Velocity thus
[tex]F_L=2qvB[/tex]
Force on particle will be doubled
