(A) If you treat an electron as a classical rigid sphere with radius 1.20×10^−17 m and uniform density, what angular speed ω is necessary to produce a spin angular momentum of magnitude √3/4 ℏ? 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. (B) Use the equation v=rω relating velocity to radius and angular velocity together with the result of Part A to calculate the speed v of a point at the electron's equator. Express your answer in meters per second to three significant figures.
