The electric potential is 4 Volts at x = 0 meters and 6 Volts at x = 1 meter. If the electric potential at x = 1 meter changes to 12 Volts and the electric potential at x = 0 meters remains 4 Volts, by how much does the strength of the average electric field between the two points change?
(a) Quarters
(b) Halves
(c) Stays the same
(d) Doubles
(e) Quadruples
