when a pressure measuring device is immersed in a liquid, a restoring Force of 2N is exerted by the spring. if the area of cross section of the Piston is 10cm^2, what pressure does the fluid exert on the piston?

The pressure experienced in both cases would be same. So, as
P = F/A
F1/A1 = F2/A2
or the force on the second piston will be
F2 = (F1/A1).A2
by substituting appropriate values we get
F2 = (F1/A1).A2
F2 = (2 / 10x10-4). 100 x 10-4
P = F/A
F1/A1 = F2/A2
or the force on the second piston will be
F2 = (F1/A1).A2
by substituting appropriate values we get
F2 = (F1/A1).A2
F2 = (2 / 10x10-4). 100 x 10-4
