Does the speed of the electron increase?
sqrt(vx^2+vy^2) > vx
If so, where does the energy come from?
The plates are charged but not connected to a voltage source, so the charge does not change.

God wills it.

no one knows
maybe conservation of energy doesn't apply here

There's the magnet hidden behind the drawing

>> No.2734084

energy comes from the place the electrons go to when they hop from orbital to orbital. Same place they go when the do that tunneling thing.

The charge's potential energy is converted into kinetic energy. Nothing mysterious about it.

What is the charge's potential energy before entering the deflecting field?

I'm not 100 percent sure on this because the only direct answer I got was from someone else who wasn't 100 percent sure but it makes ass loads of sense.

The electron never changes speed it only travels in longer or shorter lines of 'least resistance'. I mean when you're talking about things at that scale everything is a vacuum pretty much. However you should note that this doesn't mean there is never any acceleration since a change in vector of anything's direction directly implies an acceleration. So yeah, I'm sure there's a lot to be said about that

Thank you. That's at least something to think about.

Ask yourself this OP:
Does the speed of a falling object increase?
Is so, where does the energy come from?

LMFAO. Potential energy changes into kinetic energy. That explains it all.

Again, what is the electron's potential energy before entering and after leaving the field?

>> No.2735221

>>2734725

Outside the field it is zero. Potential energy is only defined within the field.
