How Does Zero Gravity Affect the Tension in Strings of Charged Bodies?

Click For Summary
SUMMARY

The discussion centers on the calculation of tension in strings supporting two identical charged bodies in a zero-gravity environment. The expected formula for tension is kq²/4l, where k is Coulomb's constant, q is the charge, and l is the length of the strings. Participants emphasize the need for a structured approach to problem-solving, including a clear problem statement, relevant equations, and an attempt at a solution. Additionally, it is noted that the expression kq²/4l does not have the dimensions of force, indicating a misunderstanding in the calculation of tension.

PREREQUISITES
  • Understanding of Coulomb's Law and electrostatic forces
  • Familiarity with the concept of tension in strings
  • Basic knowledge of orbital mechanics
  • Ability to format and manipulate mathematical expressions
NEXT STEPS
  • Study Coulomb's Law and its applications in electrostatics
  • Learn about the dynamics of tension in strings under various forces
  • Research the principles of orbital mechanics and their effects on physical systems
  • Explore dimensional analysis to verify the correctness of physical equations
USEFUL FOR

Students of physics, particularly those interested in electrostatics and mechanics, as well as educators seeking to clarify concepts related to tension and forces in charged systems.

Member advised to use the homework template for posts in the homework sections of PF.
Two identical small bodies each of mass m and charge q are suspended from two strings each of length l from a fixed point. This whole system is taken into an orbiting artificial then the tension in strings is...
The answer has to be kq2/4l but how? Can someone please explain? Plus its not a homework and I'm new so id be glad if someone could help.. Thanks a lot inanticipation!

Sorry to be a stickler for rules, but Physics Forums requires homework problems to be written following a specific format.

That doesn't actually give the template. Hmm. I'm not sure where the template description can be found, but it's pretty simple. You have three numbered sections with the following titles (in bold):

Homework Statement



Homework Equations



The Attempt at a Solution

 
Hello, Ujjwal28. Welcome to PF!.

Even though you state that your question is not homework, it does have the "feel" of a homework problem. Filling out all three parts of the template will assist the homework helpers in responding to your question.

1. Regarding the problem statement, it appears that you left out something in your problem statement after "orbiting artificial".

2. Are there any relevant equations that you can list?

3. You have not shown any attempt at a solution. Tell us how you are thinking about the problem. For example, can you describe how you think the two strings are oriented as they orbit?

---------------------------------

I assume that your expression kq2/4L is meant as kq2/(4L). (You can use the tool bar to format expressions with superscripts, etc.) Note that kq2/(4L) cannot be the tension since this expression does not have the dimensions of force.
