SUMMARY
The discussion centers on calculating the electric field produced by a uniform charge density on an infinite plane, specifically using Gauss's law. Participants emphasize the importance of using the correct formula, noting that the unit of electric field is not C/m². The standard equation for the electric field near a uniformly charged infinite plane is referenced, and users are encouraged to consult their lecture notes for this equation. A link to HyperPhysics is provided for further clarification on the topic.

Welcome to PF!
While posting in the homework-help forum, you need to show your own attempt at a solution first.

You are using an incorrect formula. This is why your answer is both numerically and dimensionally incorrect. The unit of electric field is not C/m2.
You have an infinite plane with a uniform surface charge density. The electric field at a point near such plane is given by a standard equation.
If you have covered Gauss' law in class, that equation should be in your lecture notes. Can you find that equation?
We cannot give direct answers here. All we can do is point out mistakes and provide hints.

This is the equation we deal with in Gauss's law. We didn't solve an example of this question, so I can't understand
