Question
A closed cubical chamber resting on the floor contains oil and a piston. If you push down on the piston hard enough to increase the pressure just below the piston by an amount p, which of the following statements is correct? (There could be more than one correct choice.)
The pressure on the sides of the chamber will not increase.
The increase in the force on the top of the chamber will be the same as the increase in the force on the bottom of the chamber.
The pressure everywhere in the oil will increase by p.
The pressure at the bottom of the oil will increase by more than p.
The pressure at the top of the oil will increase by less than p.
The pressure on the sides of the chamber will not increase.
The increase in the force on the top of the chamber will be the same as the increase in the force on the bottom of the chamber.
Explanation / Answer
as the piston moves down the volume of the cubical chamber upto which the oil contains decrease atomatically the pressure in creases.
The increase in the force on the top of the chamber will be the same as the increase in the force on the bottom of the chamber
The pressure everywhere in the oil will increase by p.
