Finding electrostatic potential energy

In summary, the conversation discusses the concept of electrostatic potential energy and its relation to dipole moments. It is noted that the potential energy is generated by the repulsion of negative charges and that the potential at the negative charge is the most negative. It is also mentioned that two adjacent charges produce more potential than one.

Homework Equations


PE = -Fdcos(theta)
PE = -(qE)dcos(theta)
PE= -pdcos(theta) or PE = - pd since all the angles here are nice.
where p is dipole

beyond trying to find what looks like the answer, I'm not sure

many thanks!

hi chiddler! :smile:

hint: which ones do you think would feel most "springy" if you tried to push them together? :wink:

hey and thanks for the response!

that's a nice way to put it. C is clearly the most springy.

Now I'm trying to translate this concept to generating electrostatic potential energy. The reason there exists this potential energy, besides the obvious repulsion, is that negative charges spontaneously move up in potential. So...the potential at the negative charge can be considered most negative and to move up is to move away.

and two adjacent charges produce more potential than one.

well that was easy...
 

1. What is electrostatic potential energy?

Electrostatic potential energy is the energy stored in an object due to its position in an electric field. It is also known as electrostatic potential or electric potential energy.

2. How is electrostatic potential energy calculated?

The electrostatic potential energy is calculated using the formula U = kQq/r, where k is the Coulomb constant, Q and q are the charges of the two objects, and r is the distance between them.

3. What factors affect the electrostatic potential energy?

The electrostatic potential energy is affected by the magnitude of the charges, the distance between the charges, and the medium between the charges, as well as any external factors such as electric fields or other nearby charges.

4. What is the relationship between electrostatic potential energy and work?

Work is done when a force is applied to move a charged object against an electric field. The work done is equal to the change in electrostatic potential energy, as given by the formula W = ΔU.

5. What are some real-life applications of electrostatic potential energy?

Electrostatic potential energy is used in many everyday devices, such as capacitors, batteries, and generators. It is also important in understanding the behavior of lightning, the functioning of electronic devices, and the stability of atoms and molecules.
