Astudent is doing a lab experiment in which she uses diffraction to measure the width of a shaft of her hair. she shines a 530 nm green laser pointer on a single hair, which produces a diffraction pattern on a screen 1.2 m away. the width of the central maximum of the pattern is 14 mm. a. what is the thickness of the hair? (91µm) b. if she chose a wider shaft of hair, how would this change the width of the central maximum? (b): for a single slit, we know that a wider slit gives a narrower pattern; the same is true for the hair.

Along the line connecting the two charges, at what distance from the charge q1 is the total electric field from the two charges zero? express your answer in terms of some or all of the variables s, q1, q2 and k =14ï€ïµ0. if your answer is difficult to enter, consider simplifying it, as it can be made relatively simple with some work.
