Question

what is pascals law? explain with the exampels

Answer 1

Pascal's law says that when pressure is placed on a fluid in a container, the pressure will disperse equally to all parts of the container. That is, the pressure of fluid furthest away from the pressure point, and the pressure of fluid closest to the pressure point will be the same — it does not diminish, for example, with distance.

or

Pascal's law or the principle of transmission of fluid-pressure is a principle in fluid mechanics that states that pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid such that the pressure variations (initial differences) remain the same. The law was established by French Mathematician Blaise Pascal.
Pascal's principle is defined as​
A change in pressure at any point in an enclosed fluid at rest is transmitted undiminished to all points in the fluid​.

Answer 2

It state that when equally pressure is applied to any part of enclosed liquid it is transmitted equally in all directions with undiminished force and acts at right angles to the surface of vessels
for example
the walls of the dam especially think it from the way so as to with stand huge pressure
