I apologize for not following the pattern cause this isn't really a problem just a case that was mentioned in the lecture and i didn't understand

This problem is driving me mad suppose that we have a positive charge inside a non conducting spherical shell uniformly charged the charge is at a random place inside the shell but not in the center the textbook says the charge will feel no force from the charges of the shell and the...

:bugeye::eek::cry: how will I face him than ?

btw did you try this expirement or do you have a source you know so I can back myself up

I wouldn't care if he believe me or not I only want to know since I couldn't do the experiment by my self :biggrin:

I have to agree on this because on of my teachers said it won't show any voltage because threre is no salt bridge although I tried to explain that voltage doesn't need current but he didn't agree :cry: so I'm stuck

IMHO so that's not sure ?

I don't mean to be a bother but i have a problem with an electrochemical cell here is the link if you would like to give me a hand https://www.physicsforums.com/showthread.php?p=3317518#post3317518"

any ideas?

thanks man I really apreciate it:biggrin:

what about the first poin of the circular path is there any vertical acceleration ? the body started with no speed and I don't know there is something which make no sense in this when i calculated the force it was 2400 N (nothing wrong ) while mg = 800 N

Homework Statement let's say we have an electrochemical cell composed of 2 cups each cup contain a metal and the ions of that metal and an acidic componment like H2so4 the two cups arent attached with any kind of conductor if we try to measure the voltage with a voltmeter would it detect...

can you explain little further please?

I wouldn't say that how can a skater's feet stand such a force this sport would have been banned if it was so

ok forget that problem imagine this situation with me ok ? a skater moves in that 1/4 circle than it moves to a flat surface there is no friction in it in the transition point (the end of the circular path and the start of the flat area ) does this body have a vertical acceleration if so why...
