Question

Most workers in nanotechnology are actively monitored for excess static charge buildup. The human body acts like an insulator as one walks across a carpet, collecting-50 nC per step. What charge buildup will a worker in a manufacturing plant accumulate if she walks 33 steps? Number nC How many electrons are present in that amount of charge? Number electrons If a delicate manufacturing process can be damaged by an electrical discharge greater than 10^12 electrons, what is the maximum number of steps that any worker should be allowed to take before touching the components? Number steps

Explanation / Answer

Q = (-50 nC) (33)

Q = - 1650 nC .......Ans

Q = n e

- 1650 x 10^-9 = n (-1.6 x 10^-19)

n = 1.03 x 10^13 electrons ........Ans

Q = (-1.6 x 10^-19) (10^12) = -1602 x 10^-9 C

Q = - 160 nC

steps = -160 / - 50 = 3.2

So maximum 3 steps. .......Ans
