Point charge dynamics near a grounded conducting plane

摘要

Point masses under the influence of Newtonian gravitynand point charges under the influence of Coulombic attractionnexperience a 1/ r2 force. Particles will approach one anothernaccording to Newtonian dynamics and, if released fromnrest, will reach the force center in a time that is proportionalnto the initial separation to the three-halves power.1–5 However,nthis result is plagued by superluminal u0001faster than lightnspeedu0002 transport and hence cannot be formally correct.
