Archimedes principle states that"when a body is partially or wholly immersed in a liquid, it experiences an upthrust which is equal to the weight displaced by it."
Pascal's law states that "when pressure is applied on a liquid enclosed in a vessel, it is transmitted equally in all directions." The two instruments based on Pascal's law are:
When a body is immersed partially or completely in a liquid, the resultant force on the body is called upthrust or buoyant force.
The two factors which affect pressure due to the liquid contained in a vessel are as follows:
P= F/A [definition of pressure]
or, P= m*g/A [since, F= mg]
or, P= d*v*g/A [since, d= m/v or, m= d*v]
or, P= d*A*h*g/A [since, V= A*h]
Therefore, P=d*h*g
The importance of gravity force are as follows:
