Gaussian Shell and net electric field

Homework Statement

Homework Equations

σ=q/(4πr^2)→q=σ(4πr^2)
E=q/(4πEod^2)
E=(4πr^2σ)/(4πEod^2)

The Attempt at a Solution

So the first thing that i could include was that the point p was inside Shell 1 and therefor would not be affected by Shell 1.

So it should be a fairly simple plug in the variables sort of problem
E=(4π(.017m)^2*(3.3E-6))/(4π(8.99E-9C)(0.104m-0.024m)^2)
E=16.5757 N/C

Looks ok. Is the answer rejected?

I used 899E-9 as Coulomb's constant. I believe that was my mistake.

That's the one thing I did not check.

Silly me.
