An electron experiences 1.2*10^-3 force when it enters the external magnetic field, B with A velocity V, what is the force experienced by the electron if the magnetic field is increased two times and the velocity is decreased to half?

Question

An electron experiences 1.2*10^-3  force when it enters the external magnetic field, B  with A velocity V, what is the  force experienced by the electron if the magnetic field is increased two times and the velocity is decreased to half?

farcher · Answer

F = B q v 

So now rewrite the equation with the new magnetic field (2B) and the new velocity (V/2) and what do you get?
