I have read these questions:
And it made me curious.
Now let's imagine in vacuum, in gravity free space, we have a metal box (square cube symmetrical) at rest (at least not accelerating), so that the metal box's sides are all electromagnetically repelling.
Let's say there we could place a free electron inside the box, and so the electron would be repelled by all sides of the box. Let's say the sides carry all the same charge.
In this case, would the electron ever be able to slow down inside the box because all sides are repelling it? Every time the electron tries to move close to a side, it will push it back towards inside.
Will this mechanism with time slow the electron down, when all the forces equal out and the electron will find rest at the center of the box? Since the box is symmetrical, there should be a center point where the net charge is 0.
- Will the electron ever find equilibrium at the center point and slow down there enough to stay at rest? Has an experiment ever been done to try to slow down an electron?
