i have been studying pressure and hydrostatics
and i stumbled upon this
now imagine a container filled with water , and there is a cube in the water
now i know that the weight of the displaced water = the upthrust force
but what bothers me is , how is the water pressure at a certain level the same even after the Cube is inserted , for instance water pressure at POINT B is the same even when the bottom of the cube is exactly at point B * 3 meters from the top of water for instance* , shouldn't it increase ? and if it increases shouldn't it cause more upthrust force and therefore suspend the cube in water ? according to Newtons law every action has a reaction , now i suppose water reaction should be equal to the cubes weight and therefore suspend it ?
if the pressure doesn't change then this explains why the cube sinks , but again how is it constant ?
if i am wrong after all , can you tell me what causes pressure at the bottom of the cube , if it is atoms being compressed , then i should be right because the cube will compress them more causing them to suspend the cube
