- If the electric potential at a point in space is considered to be zero, what can be said with certainty about the electric field at the same point?How much work is required to set up the arrangement of charges shown in Figure if Q = - 3 µC? Assume that the charged particles are initially infinitely far apart and at rest. Take the potential to be zero at infinity. 3 m 4 mNear the surface of the Earth, there is an electric field (even when there is no thunderstorm). Usually, the air is positively charged, and the ground is negatively charged, creating an electric field of typically 100V/m, pointing vertically down. This phenomenon is known as “atmospheric electricity". In our discussions below, treat this electric field as uniform, so that we have plane symmetry in the system. Human body has an average dielectric constant of ɛ, = 50. Under the atmospheric electricity, the human body can be treated as a linear dielectric. a) For a person standing on the surface of the Earth, calculate the electric field inside the human body due to the atmospheric electricity. b) For the same person, calculate the polarization inside the body due to the atmospheric electricity. c) For the same person, calculate the surface bound charge density on the top of their head and the surface bound charge density on the bottom of their feet. d) Briefly explain why you cannot…
