When the idea of electron spin was introduced, the electron was thought to be a tiny charged sphere (today it is considered a point object with no extension in space). Under the assumption that the electron is a sphere with the charge at the equator of the surface. Find the speed of the charge on the equator that is needed to produce a spin angular momentum equal to ¯h/2. Use the classical radius of the electron, re = 2.8 fm = 2.8 × 10?15 m.

(a) Compare the result to the speed of light c. Based on your answer, can the classical model explain the electron spin

Part A If you treat an electron as a classical rigid sphere with radius 1.10×10−17 mm and uniform density, what angular speed ωomega is necessary to produce a spin angular momentum of magnitude √3/4ℏ? Use h = 6.63×10−34 J⋅s for Planck's constant, recalling that ℏ=h/2π, and 9.11×10−31 kg for the mass of an electron. Express your answer in radians per second to three significant figures.
