Electric Field Sketch: Ex vs. x & Fx vs. x Homework

Click For Summary
SUMMARY

The discussion focuses on sketching electric field (Ex) and force (Fx) diagrams in relation to potential difference (pd) graphs. The key equation discussed is Ex = -dV/dx, which defines the relationship between electric field and potential. The user seeks clarification on whether the Ex sketch should transition from positive to negative if the pd graph transitions from negative to positive. The consensus indicates that the Ex graph will indeed be an inverse representation of the pd graph when the potential depends solely on x.

PREREQUISITES
  • Understanding of electric fields and potential difference
  • Familiarity with calculus, specifically differentiation
  • Knowledge of graphing techniques for physics concepts
  • Basic principles of electrostatics
NEXT STEPS
  • Study the implications of the equation Ex = -dV/dx in various contexts
  • Explore graphical representations of electric fields and potentials
  • Learn about the relationship between electric force (Fx) and electric field (Ex)
  • Investigate how potential difference affects electric field strength in different materials
USEFUL FOR

Students and educators in physics, particularly those focusing on electrostatics and electric field concepts, as well as anyone preparing for exams involving these topics.

Homework Statement


Sketch 2 diagrams 1 showing Ex against x and 1 showing Fx against x


Homework Equations





The Attempt at a Solution


I have drawn a graph showing potential difference against x and have been asked to produce a sketch showing Ex and Fx relating to this graph but I am unsure how to do this, will my sketch of Ex be going from positive to negative if my pd went from neagative to positive
Thanks in advance cerium

What is the equation that determines the electric field from its potential? What does that equation reduce to when the potential depends only on x?
 
Equation relating electric field and potential is Ex= -dV(r)
dx
if it just relies on x then is it just an inverse sketch of the pd graph
