I'm confused. How can there be a charge density if the electric field is one dimensional?
PsychonautQQ said:I don't know if I'm saying what I'm thinking clearly. I mean it looks the problem states that there is NO E field in the x and y domains, and yet if there is an E field in the Z domain, there can still be an E field in the X and Y because it is a distance r away from the Z. Dig?
An electric field GRE problem is a type of question commonly found in the GRE (Graduate Record Examination) physics section. It involves calculating the electric field at a given point in space, typically caused by a single point charge or a collection of charges.
The electric field is calculated by dividing the force exerted on a test charge by the magnitude of the test charge. Mathematically, it is represented as E = F/q, where E is the electric field, F is the force, and q is the test charge.
The unit of electric field is newtons per coulomb (N/C) in the SI (International System of Units) system.
The strength of an electric field is affected by the magnitude and distance of the charges creating the field. As the distance between charges increases, the electric field strength decreases. Additionally, the presence of conductors or insulators can also influence the strength of the electric field.
Electric field GRE problems can be solved by using Coulomb's law, which states that the force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Other strategies include using vector addition for multiple point charges and integrating to find the electric field for continuous charge distributions.
