Hi there!

I have a question about the Faraday's Nested Sphere Experiment, please see the attached pdf. I wonder why equation (1) and the electric field's equation ( coming after (1) ) consider only the charge Q. Why there aren't charge -Q in the equation?

Ps. I'm thinking about point charges. When you have two charges: +Q and -Q, and you want to find the electric field at point x. You need to put both +Q and -Q in an equation:
