A manufacturer claims that a carpet will not generate more than 4.9kV of static electricity. What magnitude of charge would have to be transferred between a carpet and a shoe for there to be a 4.9kV potential difference between the shoe and the carpet. Approximate the shoe and the carpet as large sheets of charge separated by a distance d = 1.0mm. Area is not given in the question. Could someone please explain how to do this question in detail? Thank you in advance.
