Question

SpongeBob SquarePants, a popular television character made of spongy material WIl dlL optimistic disposition, barely floats in a container partly filled with water. If the container is sealed and then pressurized above atmospheric pressure the "spongy one" will (a) sink (b) remain at the same level (c) rise

Answer 1

If it is just floating then weight of the body is equal to buoyent force acting on it. If pressure is increased, weight of the body does not change and buoyant force does not change because it depends on density of liquid. So it will remain in same level
