Help Solving Physics Problem: Point Charge and Rod of Charge

Click For Summary
SUMMARY

The discussion revolves around solving a physics problem involving a positive point charge q and a uniformly charged rod of length L with total charge Q. The solution approach involves dividing the rod into infinitesimal slices, calculating the force from each slice, and integrating these forces over the length of the rod. The problem is sourced from "Physics Vol 2—Edition Fifth" by David Halliday and Robert Resnick, indicating its academic context.

PREREQUISITES
  • Understanding of electrostatics, specifically Coulomb's law.
  • Knowledge of calculus, particularly integration techniques.
  • Familiarity with the concept of charge distribution.
  • Basic physics concepts related to forces and fields.
NEXT STEPS
  • Study the principles of Coulomb's law in detail.
  • Learn about charge distribution and its effects on electric fields.
  • Practice integration techniques, focusing on applications in physics.
  • Explore examples of force calculations involving continuous charge distributions.
USEFUL FOR

Students of physics, particularly those in introductory courses, and anyone seeking to understand electrostatics and force calculations involving charged objects.

Hi Friends I am student of BsCs- 1st Semester,

I am facing problem to solve a question of physics. I have tried my best to solve it but I am fail, can anyone do it for me I will thank to him.

Here Is The Question

Find the force on a positive point charge q located a distance x from the end of a rod of length L with uniformly distributed positive charge Q. See Fig



This Question Is Taken From Physics Vol 2—Edition fifth by
David Haliday (university of pittsburg)
Robert Resnic

Welcome to PF!

Hi urduworld! Welcome to PF! :smile:

(btw, never bump your questions in the first 24 hours … people are much more likely to answer a thread with 0 replies :wink:, and half PF's members are asleep now anyway! :zzz:)

Hint: divide the rod into slices of thickness dy and charge Qdy/L, find the force from each slice, and integrate from x to x + L …

what do you get? :smile:
