Question

Part A

If you treat an electron as a classical spherical object with radius 1.3010?17m , what angular speed ? is necessary to produce a spin angular momentum of magnitude 3/4?????? Use h = 6.6310?34J?s for Planck's constant, recalling that ?=h/2?, and 9.1110?31kg for the mass of an electron.

Express your answer in radians per second to three significant figures.

Part B

Use the equation v=r? 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.

Explanation / Answer

Moments of inertia of solid sphere with radius r:

I = (2/5)mr
