Question

An electron is moving through a magnetic field. If the velocity of the electron is doubled, then

Answer 1

Answer:Force is doubled

Step-by-step explanation:

Given

Speed of Electron is doubled then

According to Lorentz theory Force experienced by Charge particle in a magnetic field

`F_L=q(v* B)`

where q=charge on particle

v=velocity of particle

B=magnetic Field

Supposing Magnetic Field is Perpendicular to Velocity thus

`F_L=2qvB`

Force on particle will be doubled
