Coulombs Law and Electric Charges

Click For Summary

Homework Help Overview

The discussion revolves around a problem involving Coulomb's Law and electric charges arranged at the corners of a square. The original poster seeks assistance in determining the magnitude of the force acting on each charge due to the others.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to calculate the net force on the charges but encounters difficulties with one specific charge. Some participants question the symmetry of the problem and suggest that it may simplify the calculations.

Discussion Status

The discussion is ongoing, with participants exploring different interpretations of the problem's geometry and the implications of symmetry. There is an acknowledgment of the challenges faced by the original poster, and some guidance has been offered regarding the approach to the problem.

Contextual Notes

There is a mention of the problem's symmetry and the potential relevance of equilateral triangle properties, though the specific details of the problem setup may not be fully clear to all participants.

Likewise, this similar problem also has me stumped
A charge of 7.00 mC is placed at each corner of a square 0.80 m on a side. Determine the magnitude of the force on each charge.

Any help would be greatly appreciated!

OMG,this is funny... :smile: :smile: :smile: :smile: :smile:

Do you know what an equilateral triangle is?

I'm insulted.

Yes, I know what an equilateral triangle is. It has three sides of equal length, and all three angles are 60 degrees. As I stated, I found the net force on two of the points, but Q(1) is giving me issues. Obviously the way I'm trying is wrong, so I'd like help, thank you.
 
You deleted the problem.Anyway,since you know what a equilateral triangle is,u might use the fact that the problem is symmetric (actually the geometry) so the directions of the forces are equivalent.If the charges were all 3 equal,then the problem would b solved if u managed to find the net foce acting only on one angle,since on the other two is practically the same,in modulus,of course.

Daniel.
