Problem 4.25 If electron, radius
[4.138]
4πεmc2
What would be the velocity of a point on the "equator" in m /s if it were a classical
solid sphere with a given angular momentum of (1/2) h? (The classical electron radius,
re, is obtained by assuming that the mass of the electron can be attributed to the energy
stored in its electric field with the help of Einstein's formula E = mc2). Does
this model make sense? (In fact, the experimentally determined radius of the electron is
much smaller than re, making this problem worse).
Prove that F= m (2x/t^2) from equations (2.1) – (2.4).
