A proton and an electron enter perpendicular to the direction of the magnetic field. The speed of the proton is twice the speed of the electron. What is the ratio of the force experienced by the proton to the electron?

Answer 1

force=Bqv so if B is the same, q is equal in magnitude, then if one is double v, the force is double.

Answer 2

so is it a 1:2 ratio then? I have the options of 1:2 , 2:1, 1:3, and 3:1 on my homework.

thanks for answering

Answer 3

oh no sorry nevermind it would be 2:1.. got it.

Thanks man
