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...
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
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

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...
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...
