[15 points] A small sphere of charge q = 8 [μC] hangs by a thin wire between two parallel infinite plates of charge separated by a distance d = 83 [cm]. The plates are insulating and have charge densities to and -o. At the equilibrium, the sphere is exposed to an electric force of magnitude Felectric = 5.35 x 10-5 [N]. Plate-1 K 0 Plate-2 1. [3 Points] Which of the plates carries the positive charge density to ? 2. [2 points] Find the net electric field vector (Enet) between the two plates. Enet = [N/C] 3. [3 points] Find the value of the charge density +o. +o= [C/m²] 4. [5 Points] Assuming that the electric potential on plate-1 is 70 [V], find the electric potential on plate-2. V₂ = [V] 5. [2 Points] What is the magnitude of the net electric field on the right side from the two plates. Enet [N/C]
