Will a 100 kg buoyant force lift a 90 kg weight attached to a lever and wedge?

hi..
i have a problem that i need to solve..
in the attached mage, there is a submerged object in water cousing na upward lift force of 100kg. above it is a lever with a weigh attached to it weighing at 90kg. wll this weight difference be enough to move the metal wedge from point a into point d, provided that the wedge is attached to a rope that will slide it along the yellow surface as it goes up out of the water.

I Think That It Would All Have To Do With How Hard Are You Pulling The Rope.
