text: This quantity appears in the first row and column of the Faraday tensor.
full_question: This quantity appears in the first row and column of the Faraday tensor. Potential energy due to the presence of this quantity is equal to one-half permittivity times the volume integral of the magnitude of this quantity squared. The Poynting vector crosses this quantity’s vector with the (*) H field, and this quantity is constant between parallel plates in a capacitor. If charges are stable, then Coulomb's law can be used to find this quantity which is measured in Newtons per coulomb. For 10 points, name this field symbolized with an E.
first_sentence: This quantity appears in the first row and column of the Faraday tensor.
