If I had a marble tied to a string traveling in a circle on a frictionless table at a constant velocity, are there any forces that act in the opposite direction of the string's tension? What are they?

    The tension of the string creates a pull toward the center which is called centripetal force. By newtons third law, all forces come in an action-reaction pair. In the case of centripetal force, the reaction is a force outward called centrifugal force (centri=center, fugal=away from), which is exerted by the marble on the string.

    as i had learned it is always center seeking, it being a force which is perpendicular to velocity.

    the force of the string always pulls the object toward the center, but the reaction force of the object itself is outward

    of course, if that was center seeking as well the object would just fly to the middle
