I am trying to wrap my head around the intuition you have here. You start with a scale with no weights on either side. It has zero...

I think you've lost your reason in this thread and should maybe take a break and come back when your head is a bit clearer. How many...

If the string pulls a mass of 10kg with a force of 200N, then the mass will accelerate against gravity. Not only that, but the force...

The definition of tension is the force exerted by the rope or string. It can't exert a force at one end and not the other, so you must...

I don't want it explained. I want a formal solution.

I don't know many many times and how many different ways it needs to be explained.

I get that, if you hung a 10kg mass from the ceiling, there is 10kg pulling down and 10 kg pulling up. I think that's the crux. All the...

No, it would read 6lb if I had 3lb of bananas hanging off one side and 3lb off the other side.

Or, 200N if you want to calibrate it that way!

But forces are vectors. That's -100 N on the left and +100 N on the right for a total of 0 N. No surprise there. The rope is not...

Define it as 20kg then! It won't change the physics. As above, you'll just need to use ##F = T/2## in your free-body diagrams.

You could, and then you would indeed get a wave function as an answer. If the process creating the electron allows the electron to be...
