22. As a person moves about in a dry environment, electric charge accumulates on the person's body. Once it is at high voltage, either positive or negative the body can discharge via sparks and shocks. Consider a human body isolated from ground, with the typical capacitance 150 pF. A) What charge on the body will produce a potential of 10.0 kV? B) Sensitive electronic devices can be destroyed by electrostatic discharge from a person. A particular device can be destroyed by a discharge releasing energy of 250 µJ. To what voltage on the body does the situation correspond?
