... This means that the kinetic energy of an electron must exceed 20 M eV if it is to be inside a nucleus. Experiments show that the electrons emitted by certain unstable nuclei never have more than a small fraction of this energy, from which we conclude that nuclei cannot contain electrons. The electro ...

... Because the force on the alpha particle by the electric eld is in the same direction as the velocity of the particle, then the particle will speed up as it travels toward the negatively charged plate. As a result, its kinetic energy increases. Conservation of Energy tells us that this must be accom ...
