Question

Which law states that the magnitude of pressure within fluid is equal in all parts?

Answer 1

Here an enclosed container fluid will be transmitted without a change in magnitude to every point of the fluid and to the walls of the container. There is an equal increase at every other point in the container

Complete step by step Solution:
A substance whether it’s liquid, its gas that is capable of flowing and that changes its shape at a fixed rate when acted upon by a force frequently it changes its shape.
So let’s understand what you mean by the pressure exerted by fluid
Pressure exerted by a fluid at any point within that fluid, so let us assume that the fluid is incompressible and at rest.
So, Pressure within a liquid depends only on the density of the liquid
Pascal's law says that pressure applied to an enclosed fluid will be transmitted without a change in magnitude to every point of the fluid and to the walls of the container. So here the pressure at any point in the fluid is equal in all directions.
$P = \dfrac{F}{A}$
Where P is the pressure
F is the force
A is the area
These three factors affect each other.
Law its application
1. automobiles
2. hydraulic brake system
3. hydraulic jack
4. hydraulic press
5. hydraulic machines
This equation proves that the pressure is the same at all points at the same depth.

Additional information:
Pascal's law states that a change in pressure at any point in an enclosed fluid is transmitted equally throughout the fluid.

Note:
Check whether the pressure is equal or not. It’s enclosed or not. Whether it’s in which state solid, fluid or liquid Pressure within a liquid depends only on the density of the liquid. To calculate we need to calculate how much force it apply on how much surface how much pressure it acquires
