[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 = 77 [cm]. The plates are insulating and have charge densities to and -6. At the equilibrium, the sphere is exposed to an electric force of magnitude Felectric = 8.25 x 10-5 [N]. Plate-1 K d 1. [3 Points] Which of the plates carries the positive charge density to ? 0 Enet 2. [2 points] Find the net electric field vector ( Enet) between the two plates. [N/C] = q Plate-2
3. [3 points] Find the value of the charge density +o. to = 4. [5 Points] Assuming that the electric potential on plate-1 is 80 [V], find the electric potential on plate-2. V₂ = [V] [C/m²] 5. [2 Points] What is the magnitude of the net electric field on the right side from the two plates. Enet = [N/C]
