I know that if density of an object is equal to density of fluid, the object will be fully submerged hovering right underneath the fluid.
My questions related to this concept are:
1. If the density of the object is extremely slightly greater than the density of the fluid, will the object look as if it is suspended more under the fluid than at the horizon, but it is actually slowly accelerating to the bottom?
2. If my premise for 1. is wrong, how can an object be fully suspended in water and be lower than at the surface of the fluid without accelerating downward.
3. Lastly, if we were to have a scale underwater, would the apparent weight of an object with equal density to fluid density be zero?
