Dale replied to the thread Graduate Horizontal component of the electric field of an infinite uniformly charged plane.Sure, you can pose it many different ways. But they do not change the mathematical facts I mentioned above. The terms that you obtain... -
Dale replied to the thread Graduate Horizontal component of the electric field of an infinite uniformly charged plane.It is a mathematical fact that the terms that you obtain are included in the constant of integration. So, it is a mathematical fact that... -
Dale reacted to PeroK's post in the thread High School An apparent contradiction between Fleming's rules with
Like.
I think we had a similar thread a couple of years ago. It might be worth searching for it. I don't use hand rules, but remember the... -
Dale replied to the thread Graduate Horizontal component of the electric field of an infinite uniformly charged plane.Ahh, I was speaking of the OP. -
Dale replied to the thread Graduate Horizontal component of the electric field of an infinite uniformly charged plane.With an infinite charge distribution I don’t think that “external” is meaningful. But, yes, if you are using this as an approximation... -
Dale replied to the thread Graduate Horizontal component of the electric field of an infinite uniformly charged plane.The horizontal field is arbitrary. It can be of any size, from negligible, to same order, to much larger. Although in this case the OP... -
Dale replied to the thread Graduate Horizontal component of the electric field of an infinite uniformly charged plane.Which is what boundary values are for. -
Dale replied to the thread Undergrad Please Explain (actually explain) The Monty Hall Problem.No. I am saying that the important thing is the conditional probabilities. And I am saying that in the regular approach Monty’s... -

Like.
Yes, it does make a difference. There is a difference between an accidental result of rare luck versus the intentional act of avoiding... -
Dale replied to the thread Undergrad Please Explain (actually explain) The Monty Hall Problem.It is important because it changes the conditional probabilities. As a matter of notation, let’s call the door that the contestant... -

It changes the probabilities because it changes the relative frequencies, which one can calculate. In other words, you play the game... -
Dale replied to the thread Undergrad Please Explain (actually explain) The Monty Hall Problem.I haven’t run the numbers for all of the variations that @PeroK describes. But my educated guess is that the optimal decision will not...
