Homework Statement
An electron and a proton each travel with equal speeds around circular orbits in the same uniform magnetic field ( I tried to attach a diagram...not sure if it worked but I've described it anyways). The field is into the page on the diagram. Because the electron is less massive than the proton and because the electron is negatively charged and the proton is positively charged:
a.)the electron travels clockwise around the smaller circle and the proton travels counter-clockwise around the larger circle.
b.)the electron travels counter-clockwise around the smaller circle and the proton travels clockwise around the larger circle.
c.)the electron travels clockwise around the larger circle and the proton travels counter-clockwise around the smaller circle.
d.)the electron travels counter-clockwise around the larger circle and the proton travels clockwise around the smaller circle.
e.) the electron travels counter-clockwise around the smaller circle and the proton travels counter-clockwise around the larger circle.
Homework Equations
Right hand Rule
The Attempt at a Solution
I answered b because if you use right hand rule then the electron and proton are both going clockwise but the electron is negative so it switches directions and so the electron is going counter-clockwise and the proton is clockwise. He said that the answer is a but I don't understand why since the electron should have made it switch directions. I tried talking to him about it but he just confused me more.
