Thanks you were right about the sign, it was supposed to be -1.337 uC
Also, sorry about the location of my topic i only put it there because the course i am taking is electrical engineering and there was a section that matched exactly. I just joined the forum and i already know i will be here...
ok, formula should be:
(7.1* 10^12)/(6.24* 10^18) + (0.2*10^-6)
= 1.337 uC which is the same as the first result i got... 0_o
i am going to go with this one.
is this correct?
All right i have a simple problem but i just want to verify my results, so any help would be greatly appreciated. The problem is as follows:
7.1* 10^12 electrons are added to a body that already has a negative charge of 0.2uC(the u is micro 10^-6). Calculate the final charge on this body...
