From Pascal's law, we can say that the pressure exerted by piston 1 on the fluid will be transmitted with equal intensity to piston 2:
[tex]p_1 = p_2[/tex] (1)
The relationship between the pressure applied p, the force applied F and the surface A is
[tex]p= \frac{F}{A} [/tex]
So we can rewrite (1) as
[tex] \frac{F_1}{A_1}= \frac{F_2}{A_2} [/tex]
And from this, we can find the magnitude of the force exerted on piston 2, F2:
[tex]F_2 = A_2 \frac{F_1}{A_1}=(900 cm^2) \frac{150 N}{100 cm^2}=1350 N [/tex]
