## Homework Statement

There are two particles side by side in a vacuum with electric charge q and mass m, traveling at distance d apart, with v speed(less than speed of light). What is the ratio of magnitude of magnetic to electric force the particle exert on each other?

## Homework Equations

F(mag)/ F(elec) is the ratio

Fm= kq1q2/ r2 and Fe=qvB

## The Attempt at a Solution

Fm/ Fe

=(qvB) / (kq1q2/ r2)

= vBr2/ kq

Does this look correct? And would this ratio have no units?
