Gauss's Law with a sphere on and charge on z-axis

Click For Summary
SUMMARY

This discussion focuses on applying Gauss's Law to a scenario involving a positive charge located on the z-axis. The user seeks to demonstrate that the electric flux through a closed surface equals the charge divided by the permittivity of free space (q/ε₀). The conversation clarifies that when the charge is shifted along the z-axis, the electric field can be adjusted accordingly by modifying the function to account for the new position, specifically using the term (z-z').

PREREQUISITES
  • Understanding of Gauss's Law in electromagnetism
  • Familiarity with electric flux concepts
  • Knowledge of vector calculus, particularly surface integrals
  • Basic principles of electrostatics and charge distributions
NEXT STEPS
  • Study the derivation of Gauss's Law and its applications in different geometries
  • Learn about electric field calculations for point charges and their influence on surrounding surfaces
  • Explore vector calculus techniques for evaluating surface integrals
  • Investigate the implications of charge distribution on electric fields in three-dimensional space
USEFUL FOR

Students and professionals in physics, particularly those studying electromagnetism, as well as educators looking to clarify concepts related to electric flux and Gauss's Law.

I have a question for E&M and I feel like I am over complicating it. As the title says, the is a positive charge on the x-axis and I must prove that flux = q/εo.

Since the charge is on the z-axis, could I just add in a term (z-z') to account for the charge not being at the origin into calculating ∫E dA?

Welcome to PF;
If you already know an equation is f(x,y,z), then shifting the source a distance z' in the +z direction turns that into f(x,y,z-z') yes.
