Force between 2 parallel, charged, conducting sheets.

Click For Summary
SUMMARY

The discussion focuses on calculating the force between two parallel, charged conducting sheets with total charges Q1 and Q2. The user sets up four equations to represent the charge distribution on the inner and outer surfaces of the sheets, specifically noting that Q1in + Q2in = 0 and Q1out = Q2out. The main challenge highlighted is determining the electric field generated by these charges to compute the force. The problem is framed as straightforward, yet the user expresses confusion regarding the initial steps in the solution process.

PREREQUISITES
  • Understanding of electrostatics and electric fields
  • Familiarity with Gauss's Law
  • Knowledge of charge distribution on conductors
  • Basic algebra for solving equations
NEXT STEPS

Homework Statement


Two square parallel sheets with area>>distance between them have total charges of Q1 and Q2 on them. What is the force between them?


Homework Equations


Q1in+Q2in=0
Q1in+Q1out=Q1
Q2in+Q2out=Q2
Q1out=Q2out

The Attempt at a Solution


I set up 4 equations for the charges on the inner and outer sides of each plate (shown above)

Now I have no idea how to find the electric field from here. any help?
