How to determine the charged particles between a distance?

Click For Summary

Homework Help Overview

The discussion revolves around determining the negative charge distribution on a neutral particle (q2) in the presence of a positively charged particle (q1). The setup involves two spherical particles with specified diameters and a distance between them, raising questions about the influence of the charge on q1 on q2.

Discussion Character

  • Conceptual clarification, Assumption checking, Exploratory

Approaches and Questions Raised

  • Participants explore whether the particles are conductors and the implications of this on charge distribution. Questions arise about the center-to-center distance and the nature of induced charges on the surfaces of the conductors. Some participants inquire about the concept of "image charges" and its relevance to the problem.

Discussion Status

The discussion is ongoing, with participants providing insights into the nature of the problem and raising questions about fundamental concepts. Some guidance has been offered regarding the assumptions about the materials involved, but no consensus has been reached on a specific method or formula to apply.

Contextual Notes

There is uncertainty regarding the course level and prior knowledge of participants, particularly concerning Coulomb's Law and electric potential. The original poster seeks clarification on how to approach the problem without prior exposure to certain concepts.

I would like to determine the negative charged level on q2 particle, referring to following image, q1 is charged particle with x unit of positive charge, which q1 diameter is 80 cm, on the other hands, q2 is a neural particle, which q2 diameter is 30 cm. Both charged particles are separated in d distance.
Does anyone have any suggestions on how to determine the negative charged level on left-hand side of q2 based on the distance and positive charged level of q1? Is there any formula to determine this value?
Thanks in advance for any suggestions

Are they conductors?

Is d the center to center distance?

They must be conductors ... or else, there will be no induced charges.
 
To cupid: q1 would not need to be a conductor. If it were not a conductor, I think the problem is more difficult to solve.

To oem7110: If the spheres are conductors, then what do you know about the surface of each sphere?
 
To SammyS:
Let assume, both particles are conductors, so positive and negative charges are free to move on its surface area, and d is the center to center distance.
Does anyone have any suggestions?
Thanks in advance for any suggestions
 
The surface of each conductor will be an equi-potential surface.

Have you been introduced to "image" charges at all?

What is "image" charges?

In q2 particle, which is neutral originally, because q1 with positive charged particle is getting closer to q2, so the negative charged level on left-hand side and the positive charged level on right-hand side for q2 particle, but I don't know what happen at the top and bottom, will it be neutral?

Could you please give me any suggestions on what Image charges are about?

Do you find any lecture under MIT talking about this issue? so I can learn what "image" is about if it related to my issue.

I look forward to your reply
Thank everyone very much for any suggestions

Sorry, I've been traveling. If you haven't been introduced to image charges, then you likely are expected to do this problem by some other method.

What level is this course? At what place are you in your course?

I assume you've had Coulomb's Law. Have you learned about electric potential?
