Electric Force in a Square: Where is Best?

In summary: If you haven't been introduced to Coulomb's Law in your coursework, then the assignment must be daunting indeed.

Homework Statement

A charge +q and charge -q are placed at opposite corners of a square. will a third charge experience a greater force if it is placed at one of the empty corners of the square, or at the center of the square? explain

not very good if it doesn't involve calculations.. thanks !

You have to fill out all three parts. What do you know and what don't you know? What are some attempts you've made so far? We can't (rather, won't) help unless we know where you're stuck.

well no information is given as far as charges go, simply one being positive, and the other negative.

I was thinking that a charge would experience a greater force if it was placed at the center of the square because the distance between the two opposite charges are closer together rather then on a corner. But I'm not positive, if someone could confirm this for me.

That someone else who would confirm or deny the statement would have the same information that you do.

Why don't you see what the formulas show? What are the relative distances between the vertexes and center of a square?

No information was given to me for the question, there were no formulas given or any information in addition to what I posted... :\

I suggest that you review your text or course notes. They should have something that applies to the forces between electric charges

sadly i don't which resorted me to come here for help.. but thanks anyways though I guess i just won't bother with the assignment haha

If you haven't been introduced to Coulomb's Law in your coursework, then the assignment must be daunting indeed. If your text doesn't mention it, you may need to find a better text The web has lots of information on it if you care to do a bit of spadework.

1. What is the concept of electric force in a square?

The concept of electric force in a square refers to the force exerted by electric charges on each other when placed at the corners of a square. This force is dependent on the magnitude and direction of the charges, as well as the distance between them.

2. How is the electric force in a square calculated?

The electric force in a square can be calculated using Coulomb's law, which states that the force between two charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

3. What factors affect the strength of the electric force in a square?

The strength of the electric force in a square is affected by the magnitude of the charges, the distance between them, and the direction of the charges. It is also influenced by any other nearby charges or external electric fields.

4. Where is the best location for the maximum electric force in a square?

The maximum electric force in a square is found at the corners where the charges are located. This is because the distance between the charges is the shortest at the corners, making the force stronger.

5. How does the electric force in a square compare to other shapes?

The electric force in a square is similar to that in other shapes, such as rectangles or circles, as long as the charges are placed at the corners or edges. However, the force may vary depending on the specific shape and arrangement of the charges.
