How did you manage to get a job as technician straight out of high school??

Thanks for the welcome and the response BuV! Conventionally we say that the E Field goes from positive to negative and since there is no field inside the object that must mean the E field vector from the top plate with a positively charge surface a must be pointing towards the positive y-axis...

Homework Statement The figure shows cross-sections through two large, parallel, nonconducting sheets with identical distributions of positive charge with surface charge density σ = 1.06 × 10-22 C/m2. What is the y component of the electric field at points (a) above the sheets, (b) between them...
