hi to all..
i have the following task and seem to be stuck.
look at the image :

the yellow part is a styrofoam object in a tube (black) - only the bottom of the object is in contact with the water. the other part of the object are covered by the tube.the objects' diameter is 1ft.
what i need to know is what would be the force exerted on point C in order to plunge the styrofoam object 1 foot down into the water? so i will have a 1x1ft circular body at 10ft depth.
i've been looking up some data and it says that at 10ft depth there is a force of 1,3 kg/cm2 acting on the base of the object...
so what would be the amount of force that will be needed to counter the buoyancy of the object and make it plunge downward???
