In the text we introduced electron spin states with spin in the 2 -direction, , and states with spin f-direction, tx (+) 1-)//2. measuring the the in z-component of spin in the state e)x each with 50% probability gives the analogous states with spin 2 in the y-direction are y) = (1+> + i |-)//2 show that a measurement of the spin in the r- or 2-direction on these two each with 50% states also yields probability

A3.9 g aluminum foil ball with a charge of +4.1×10−9 c is suspended on a string in a uniform horizontal e⃗ field. the string deviates to the right and makes an angle of 30∘ with the vertical. part a part complete what information about the e⃗ field can you determine for this situation? what information about the field can you determine for this situation? only the magnitude of e⃗ only the direction of e⃗ both the magnitude and the direction of e⃗ none of the above previous answers correct part b determine the magnitude of the electric field. express your answer with the appropriate units. e e = nothing nothing request answer part c determine the direction of the electric field. determine the direction of the electric field. to the right to the left away from you toward you
