Hi all,

Since there might be one or two other people out there with a knack for figuring out interesting problems I thought I'd throw this one out.

Two positively charged objects of equal mass start out moving in parallel through a vacuum. An observer moving at the same speed and in the same direction should see them repel each other since they are like charges. However, an observer moving fast enough with respect to these objects should see a magnetic attraction overcome the electrical repulsion, causing them to come together. Why the discrepancy? Can these both be true or what will really happen? Have fun!

Matt
