Two small iron particles, each of mass 280 mg are placed at a distance 100 mm apart.
If 0.01% of the electrons from one particle are transferred to the other, find the electric force between them.
(There are 26 electrons in each atom of Fe)
(Z = 56 g/mol)

My answer is 1.31 x 10^12 N

Can anyone cross-check?

[UzzyFTW]

We do electric force with not with mass things, we do it with 1 atom which has like 10^-31 kg xD

*facepalm
Uzzy, 1 mole has 6.022 × 10^23 particles of matter so electrons can be estimated from there and their charge too.

Anyways, Phoenix, Battle and other nubs of my age would know this, pl0x check it out.

^ jesus christ how old are you!?

[SmG Pulse]

16 years and 8 months, nub :P

So, guiz, anyone know it?

[Beasty]

So your a sophmore or a junior? Lol wut is this science? Learning basic magnets like a baws [kewlz] moving electrons polarize the metal atoms- thats pretty much all i know on that subject xD and im a junior.


Oh USA Education system....

[SmG Pulse]

Just Completed Sophomore year I guess as per your education system...

Hells yeah Pulse. Same Age. I don't do physics..... I do chem though. :D

Oh physics , am just at the starting stage , i only know 1 molecule ha 6.022 * 10 ^23 , which pulse mentioned
