1. The problem statement, all variables and given/known data A piece of wood is floating in water kept in a bottle. The bottle is connected to an air pump. Neglect the compressibility of water. When more air is pushed into the bottle from the pump, the piece of wood will float with a)larger part in the water b)lesser part in the water c)same part in the water d)it will sink 2. Relevant equations 3. The attempt at a solution When more air is pushed the air pressure inside the bottle increases. But what will be its effect on floatation?
