Electric Field from Charged Cylinder | Radial Distance

Click For Summary
SUMMARY

The discussion centers on calculating the electric field from a charged cylinder, specifically addressing the common mistake of using the volume of a sphere instead of the volume of a cylinder. Participants emphasize the importance of correctly identifying the Gaussian surface for determining the charge enclosed. The correct approach involves applying Gauss's Law with the appropriate geometry to derive the electric field at a radial distance from the charged cylinder.

PREREQUISITES
  • Understanding of Gauss's Law
  • Familiarity with electric fields and charge distributions
  • Knowledge of cylindrical coordinates
  • Basic calculus for integration of electric fields
NEXT STEPS
  • Study the application of Gauss's Law in cylindrical symmetry
  • Learn about electric field calculations for different charge distributions
  • Explore the concept of Gaussian surfaces in electrostatics
  • Review examples of electric fields from various geometries, including cylinders and spheres
USEFUL FOR

Students studying electromagnetism, physics educators, and anyone seeking to understand electric fields generated by charged cylindrical objects.

You are using the volume of a sphere instead of the volume of a cylinder.
 
You should draw the Gaussian surface for which you are calculating the charge enclosed.
