SUMMARY
The discussion focuses on calculating the smallest possible distance between two electrons fired directly at each other at a speed of 3.5x10^6 m/s. The relevant parameters include the mass of an electron (me = 9.1x10^-31 kg) and the charge of an electron (qe = 1.6x10^-19 C). The conservation of energy principle is applied, where the initial kinetic energy (KE) of one electron is equated to the potential energy (PE) when they are at a distance x from the midpoint. The midpoint serves as a reference point for symmetry, allowing for a simplified calculation of the distance between the two electrons.
