The Mechanical Behavior of a Multispring System Revealing Absurdity in the Relativistic Force Transformation

Figure 5

The spring is attached to a thin, frictionless rod, which has pierced the upper plate of a parallel-plate capacitor. Since the spring force of cancels out the field force of , the tiny charge , which is attached to the lower end of the rod, is suspended statically from the standpoint of the lab observer . Both the rod and the pillar are made of nonconductive materials. On the other hand, because the spring is supposed to be located far outside the capacitor, no EM field affects it. Observer moves at along as viewed by .
