Hello all ,
I am interested in the following problem:
In an ensemble of atoms, the forces on atom A and atom B are given by the vectors Fa=Fax+Fay+Faz and Fb=Fbx+Fby+Fbz, respectively.
There respective positions are given by,
Pa=Pax+Pay+Paz and Pb=Pbx+Pby+Pbz
I have two questions:
(1) Would I be right in thinking that the dot product of Fa and Pb will give the magnitude of the force on atom A in the direction of atom B?
(2) Also, is the dot product of Fa and Fb the attractive force between the atoms?
Any help would be greatly appreciated !
