3. At a particular location near the earth's surface, weather conditions produce an electric field that has a magnitude of 259 N/C pointing directly down toward the ground. A charged piece of plastic is then released in this field. If the electric field causes an electric force on the plastic of 3e-3 N directed down toward the ground (in the same direction as the electric field), then what the magnitude and sign of the charge...
