Covered a few basics regarding the topic but very limited as you can tell. So....in the event of the object moving directly south, the resultant force would no longer be = 0. What would it then equal? In order to achieve this am I right in saying I could increase the magnitude of force B and also adjust the direction of force A? Thanks for your patience you must be pulling your hair out.

If you change those forces by adding a force with components (0, -s), where s > 0, the new resultant will be a force of s kN directed due south. You can add (0, -s) to any one of the original forces, or you could change more than one of the original forces, provided that the changes total (0, -s). Thanks from NAC54321

If I didn't want to add another force and only work with the forces I currently have. In which 2 ways would I be able to change the magnitude or direction of the current forces to ensure the object moves directly South? Thanks.

You could make any changes you like to any or all of the original forces, provided that the resultant of the changes is a force with components (0, -s), where s > 0. For example, you could change force A from having components (-800, 0) to having components (-800, -s) and leave forces B and C unchanged, or you could leave forces A and C unchanged and change force B to have components (0, -850 - s). There are infinitely many possibilities. Thanks from NAC54321
