... With four charges, there are 6 pairs: 12, 13, 14, 23, 24, 34. Let L be the length of a side. Four pairs (corresponding to the 4 sides) each contribute −kQ 2 / L while the diagonals each contribute kQ 2 / 2L . The total potential energy is thus ...

... The particle is called free body if it is no in interaction with any other body or field. Newton’s first law: It is possible to find a reference system in which the free body or particle does not experience acceleration or its speed is constant or zero. This reference system is called inertial syste ...
