Electric charges and fields

In summary: Instead, the tension would be kq/(4L). In summary, you may have forgotten to include something in your problem statement after "orbiting artificial". You may also need to list relevant equations, and you have not attempted to solve the problem.

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):

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.
 

1. What is an electric charge?

An electric charge is a fundamental property of matter that causes it to experience electrical forces. It can be either positive or negative, and is measured in units of Coulombs (C).

2. How are electric charges created?

Electric charges are created when atoms gain or lose electrons. When an atom gains an electron, it becomes negatively charged, and when it loses an electron, it becomes positively charged. These charged atoms, called ions, can then interact with other charged particles.

3. What is an electric field?

An electric field is a region of space around a charged object where the electric force can be felt by other charged particles. Electric fields are represented by lines of force, and their strength is measured in units of Newtons per Coulomb (N/C).

4. How are electric charges and electric fields related?

Electric charges create electric fields, and the strength of the electric field depends on the magnitude of the charge. The direction of the electric field is determined by the sign of the charge: positive charges create outward-pointing fields, while negative charges create inward-pointing fields.

5. What are some real-world applications of electric charges and fields?

Electric charges and fields are essential in many everyday technologies, such as batteries, electronic devices, and power generation. They also play a crucial role in natural phenomena, such as lightning and the aurora borealis.
