An aluminium nail has an excess charge of +3.2 ?CHow many electrons must be added to the nail to make it electrically neutral?so far i have that -1.6 x 10 to the -19 is the charge of one electronso +3.2 ?C.is 2 times thatso i figured the answer would be 2 x 10 ^ 19 but it's coming up as incorrect :S where am i going wrong?thanks
use the heavy duty anchors in the drywall,some are rated at 50 lbseach,i would mount the bracket to the drywall itself and forget the backboard.
of electrons electric charge / charge of one electron of electrons 3.2 x 10^-6 / 1.6 x 10^-19 electrons 2.0 x 10^13
