Potnt_3d()         Electric Potential Due to Point Charges (3 Dimensions)      2-4-2003

This program calculates the electric potential at any point P due to any number of point charges.  The charges, their coordinates, and the coordinates of the point P must be entered.  A running sum is displayed after each charge is entered.  The final result is copied to the home screen (using Copyto_h() by Samuel Stearley) so it can be more easily used in further calculations.

Copyto_h() is used in the main program.  Place both programs in the same folder, then run Potnt_3d().
