Pascal’s law || class-11th||physics || Fluid mechanics .
Statement of Pascal’s Law Pascal’s Law states that any pressure applied to a confined, incompressible fluid is transmitted undiminished throughout the fluid in all directions and acts with equal force on equal areas. Alternatively, in the absence of gravity, the pressure at any point in a fluid at rest is the same in all directions.…
