Electric charges and fields

  1. Apr 23, 2016 #1
    • 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):

    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. 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.
