If we have a rod that has no mass (and hawing no mass is the reason for this question).
(this can be approximated with wery low mass rod in space).
Now we apply force to only one end of this rod and this force is not
collinear (edit: and is perpendicular) with the rod and there are no other forces (like friction or inertion).
Is this rod suppose to rotate (around the end with applied force)
or translate(in direction of force)?
In other words, is center of rotation at zero or at infinity?
