Equations used:

Edisk= (-σ/2ε)[1-(z/sqrt(z^2 + r^2))]

Esheet= +σ/2ε

Enet= ƩE

I converted all the cm into m and plugged the numbers in. I got 3.64e10 N/C for the disk and 1.30e11 N/C for the sheet. I added the two together but my answer was wrong so i tried subtracting and still didn't get the right answer. I thought adding them would've been correct. Am I missing something?
