an electron (mass 9.11*10^-31kg) moves in a circular orbit around nucleus of mass 1.67*10^-27kg. if the radius of orbit is 5*10^-11 meters and the angular momentum is 1.05*10^-34 kg*m^2/s
find moment of inertia
angular kinetic energy
The Attempt at a Solution
to find I, we need W (angular velocity). How do i find this if i just have 2 masses and radius?
