hello dude
So force A must be acting downwards, not upwards. A 'negative' force is one that is acting in the direction opposite to what you decide to be the positive direction (Usually, upward is +ve, downward is -ve). If the object is accelerating, then the situation is different. A could be any value greater than -600N.
