Electric Field due to a Charged Disk.

Click For Summary
SUMMARY

The discussion focuses on calculating the electric field generated by a charged disk at a distance "d" along its axis, where the charge density is maximum at the center and decreases towards the edges. The user has a solution for a uniformly charged disk but seeks assistance for this specific scenario. Key to solving this problem is the formulation of the surface charge density as a function of the radial distance "r" from the center of the disk.

PREREQUISITES
  • Understanding of electric fields and charge distributions
  • Knowledge of surface charge density concepts
  • Familiarity with calculus, particularly integration techniques
  • Basic principles of electrostatics and Gauss's Law
NEXT STEPS
  • Research the derivation of electric fields from non-uniform charge distributions
  • Study the concept of surface charge density and its mathematical representation
  • Learn about the application of integration in calculating electric fields
  • Explore the use of numerical methods for complex charge distributions
USEFUL FOR

Physics students, electrical engineers, and anyone studying electrostatics who seeks to understand the behavior of electric fields from charged objects with non-uniform charge distributions.

Homework Statement


Find the electric field due to a Charged Disk at a distance of "d" which is in the disk's axis direction. The charge has it's maximum value at disk's center and decreases towards the edges.

I have the solution for uniformly charged disk but I can't figured it out for the situation above. Thank you.

Any answers?
 
What have you tried so far? No one would help you if you don't show any attempt. Start by writing the surface charge density of the disk in terms of r, the radial distance from the disk centre to any given point on the disk.
