Explanation / Answer

the worker collects -50 nC per step

a) charge builup in 33 steps = -50*33

= -1650 nC = -1.65 uC

b) number of electrons present in the charge

charge on a single electron = 1.6*10^-19C

number of electrons present = (1.65*10^-6) / (1.6*10^-19)

= 1.03*10^13

c) the delicate maufacturing process can be damged by 10^12 electrons

total charge = 10^12*1.6*10^-19 = 1.6*10^-7 C = 160 nC

number of step = 160 / 50 = 3.2 steps
