Simple suggestion.
Apply the opposite force to the ship firing the beam from the force applied to the target ship.
If you can't push/pull your target, you should at least be able to push/pull yourself towards and away from your target.
Theoretical applications: torpedoes that actually drag themselves into the target, leech drones, rapid escape from enemy capital ships while piloting a fighter, rapid bombing runs with bombers, etc.
I think that if you're able to move your own ship as well...
Push and Pull effect on weapons should work both ways
