Force between 2 parallel, charged, conducting sheets.

AI Thread Summary
The discussion revolves around calculating the force between two parallel, charged conducting sheets with charges Q1 and Q2. The user has established four equations related to the distribution of charges on the inner and outer surfaces of the plates but is unsure how to derive the electric field from this information. There is a sense of frustration as the user perceives the problem as straightforward yet feels stuck at the initial steps. Clarification on how to proceed with finding the electric field and ultimately the force is sought. The conversation highlights the challenges in applying theoretical concepts to practical problems in electrostatics.

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?

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
