Force on a part of a spherical shell on the other

AI Thread Summary
To calculate the electrostatic force on one part of a charged conducting sphere due to the other part after a plane cuts it, the initial approach involves dividing the sphere into infinitely thin discs and integrating the forces between them. This method can become complex and cumbersome. An alternative suggested is to use the Maxwell stress tensor, which may simplify the calculations. The participant expresses unfamiliarity with the Maxwell stress tensor but is open to exploring it for a more efficient solution. Understanding the Maxwell stress tensor could provide a clearer framework for solving the problem.

Homework Statement


Given there is a conducting sphere which has a charge q on it. A plane cuts the sphere into 2 form a distance r from centre. How can we calculate the electrostatic force on one part on either side of the plane due ro the other part?

The Attempt at a Solution


I tried to divide one part and divided it into infinitely thin disc. Then i calculated the force due to this disc on the other part of sphere. This was done again by deviding the other part into small parts and then finding force due to the infinitesimal disc on the other infinitesimal didc and then integrate it. Ghis process looks very messy. Is there any other way yo solve it?

Nope. But thanks for the reply. I will refer to it and try it out.

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...

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
