What is the Net Pressure in a Syringe?

[Manda_24]

Homework Statement

A nurse applies a force 4.35 N to the piston of a syringe. The piston has an area of 5.99x10^-5m². What is the pressure in the fluid within the syringe? Answer in kPa.

Homework Equations

mg/2A=$$\Delta$$P

The Attempt at a Solution

4.35/2*5.99x10^-5= 36310.518 Pa converted to 36.31 kPa

I thought I was doing this right but the program isn't accepting my answer. Is there something that I did wrong? I've been having all sorts of issues with this assignment that I thought was fairly easy.

I think pressure is just force/area

Thanks, that was right. My TA told the class that this one was just like one of our other problems but it isn't, that was part of my problem.

Net pressure in the fluid with in the syringe is
P = Pressure in side the syringe - atmospheric pressure out side the syringe.
