QUESTION 4 To minimize the influence of external magnetic fields on our experiment, we should set the device to have its magnetic field to be at 90° with respect to what? 13 degrees to the right (clock-wise) of true (or geographic) north here at Stony Brook any arbitrary starting angle true or geographic north here at Stony Brook magnetic north here at Stony Brook QUESTION 5 To find the charge-to-mass ratio of the electron, you will extract and use information from a plot of V versus ($Ir$)^2 from your Part 1 measurements. Which of these is the slope of that graph? the product of a and the earth's magnetic field ($B_E$) An algebraic expression involving both a and the charge-to-mass ratio the factor a the charge-to-mass ratio QUESTION 6 Why must we convert to radians to calculate $cos(\theta)$ in our data sheet? Google Sheets trig functions are only available in months which contain the letter "r" (in standard English spelling) Google Sheets trig functions require values less than 45 as input (Excel and many other spreadsheet programs do this too) Google Sheets trig functions default to radians as input (Excel and many other spreadsheet programs do this too) Google Sheets does not have a cosine function (Excel and many other spreadsheet programs lack this also)
