Electric Field value at distances from charge or plate.

Click For Summary

Homework Help Overview

The discussion revolves around determining the Electric Field (E) values at various distances from a single charge and from charged plates, particularly in the context of electrostatics. Participants are exploring the implications of charge distribution and surface area on the Electric Field generated by these sources.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants discuss the formula E=Kq/r^2 for a single charge and question its application to charged plates. There is inquiry into whether the surface area of the plate affects the Electric Field and how to calculate the Electrostatic Force when a charge is placed between the plates.

Discussion Status

The conversation is ongoing, with some participants affirming the use of established formulas while others seek clarification on the nature of the plates and the relationship between charge and Electric Field. There are indications of differing interpretations regarding the setup of the problem, particularly concerning the capacitor analogy.

Contextual Notes

Participants are navigating assumptions about the configuration of charges and the definitions of terms like "capacitor." There is a focus on the equations relevant to Electric Fields and forces, but the specifics of the problem setup remain somewhat ambiguous.

Homework Statement


If given a single charge (q), how would one determine the Electric Field (E) value at given distances?

How about from a plate? Would the given surface area play apart here?

Homework Equations


F=K(q1)(q2)/r^2, K= Coulomb's Constant = 9e^9 Nm^2/C^2, F=Eq, PE=qV, V=Ed

Possibly E=Kq/r^2 for the single charge? Still working on the capacitor.
 
Yes, E=kq/r^2 for a single charge. Where does it say that the plate is a capacitor?
 
Two plates are esentially a capacitor. Top plate Posotive and the Bottom plate Negative. Is there an equation to determine the Electric Field value (E,volts) at points between the plates? And what if a specific charge were placed at those points. Is there an equation to determine Electrostatic Force? Or would we just use F=k(q1)(q2)/r^2 with q1 being the plate charge and q2 being the individual charge?
