Q. Electrons with spin in the π§-direction (π§Μ) are passed through a Stern-Gerlach (SG) set up with the magnetic field at π = 60o from π§Μ . The fraction of electrons that will emerge with their spin parallel to the magnetic field in the SG set up (rounded off to two decimal places) is Β Β Β Β Β Β Β
