How can the presence, magnitude, and direction of a non-zero electric field be determined? a. Place a neutral particle in the region containing the field. If it remains at rest, there is a non-zero electric field. b. Place a neutral particle in the region containing the field. It will accelerate in the direction of the electric field. The magnitude of the acceleration can be used to determine the field. c. Place a positively charged particle in the region containing the field. If it remains at rest, there is a non-zero electric field. d. Place a positively charged particle in the region containing the fi eld. It will accelerate in the direction of the electric fi eld. The magnitude of the acceleration can be used to determine the field.
