Subject: two relativistically approaching electrons feel weaker force?‏

If two electrons travel toward each other at relativistic speed, do they feel
less force than when they approach each other slowly(or when they are stationary
to each other)? It seems that from the reference frame of each electron
approaching at relativistic speed, the electric field density look different
(decreases in traveling direction (say, x direction) and increases in
perpendicular direction (say, y direction) to traveling direction). is this true
or not?
