Problem 12: Recall that a cube has eight corners and six square facees. A point charge Q, placed at the center of a cube, produces an electric field strength of E = 150V/m, at each of the eight corners of the cube. What is the strength of the electric field at the centers of the six square faces of the cube? (A) 260 V/m (B) 50 V/m (C) 212 V/m (D) 450 V/m (E) 86.6 V/m
