Answer 2

Answer:

Hello the Question is pretty simple

According to Pascal's Law (Only for incompressible Fluids)

External Pressure applied is distributed all over the fluid .

Explanation:

So let's imagine a cylinder with 2 moveable piston at both ends.The right and left end has area A1 and A2 respectively.let us apply a force F1 on right end (A1)So pressure exerted will F1/which is distributed to the other end and the left piston will

exert a force F2 outwards on area A2 with same pressure.

So

$\frac{f1}{a1} = \frac{f2}{a2}$

cross multiplying both sides we get

$\frac{f2}{f1} = \frac{a2}{a1}$

Hope you Acknowledge my efforts.
