We will do the following processes: a) First we take three point particles of mass (m1, m2, m3) from infinity and glue them to positions (x1, x2, x3) relative to some global inertial reference system. b) We now carry three positively charged particles qi, i ∈ (1, 2, 3) from infinity and glue them to positions (y1, y2, y3) relative to some global inertial reference system. Explain of these two processes if the external world gained or lost energy? Evaluate the energy gained or lost from the outside world. Is there conservation of energy in these processes?
