**1. Homework Statement**

There is a large positively charged plate whose charge density is ##\sigma = 2.0 × 10^{-5}\frac{C}{m^2}##. What is the electric field at a point P, that is not enclosed between the plates.

**2. Homework Equations**

For an infinite sheet:

$$\vec E = \frac{\sigma}{2\varepsilon_0}\hat r$$

**3. The Attempt at a Solution**

I thought to find the field of the plate by adding, but that would be the field between two infinite planes, one with negative charge and one with a positive charge. Would that still form the electric field of a positively charged plate? So,

$$\vec E = \frac{\sigma}{\varepsilon_0}\hat r$$

Thank you in advance.
