Quizplus · Accepted Answer

As the positive test charge q moves away from the positive fixed charge Q, the electric force between them decreases due to the inverse square law. Therefore, the acceleration of q will decrease since it is directly proportional to the electric force acting on it. Hence, decreasing acceleration is the best choice.
