Chapter 6: Q23E (page 1402)
(a) If you treat an electron as a classical spherical object with a radius of , what angular speed is necessary to produce a spin angular momentum of magnitude ? (b) Use and the result of part (a) to calculate the speed v of a point at the electron’s equator. What does your result suggest about the validity of this model?
Short Answer
(a) Angular speed necessary to produce spin angular momentum of is .
(b) Speed of a point at electron’s equator is . The speed is greater than speed of light which can never be possible as per special theory of relativity so this model is invalid.
