We have investigated the energetics and stability of discrete charge distri
bution on a thin conducting disk. We have seen that the equal point charges
distribute themselves on the disk according to certain rules. It has been
found that discrete charge distribution shows different characteristics tha
n continuous charge distribution from energetics point of view. Nevertheles
s, far large number of charges these different characteristics tend to be i
dentical. (C) 2001 Elsevier Science B.V All rights reserved.
