Problem
Two large, oppositely charged parallel metal plates are separated by a distance of 0.080m, creating a uniform electric environment in the region between them. A pointlike object carrying a charge of +2.0μC is released from rest exactly midway between the plates and is observed to accelerate downward because of an electric force of 0.010N. Neglect all forces other than the electric interaction.
(a) Calculate the magnitude of the electric field present between the plates.
(b) State the direction of the electric field vector between the plates. Give your answer in words (e.g., “upward,” “to the right,” etc.).
(c) A second object carrying a charge of −3.0μC is now placed at the same point midway between the plates. Determine the magnitude and direction of the electric force that acts on this second object.
