Under normal atmospheric conditions, there exists a weak electric field near the earth's surface, pointing vertically downward, whose value is 150 N/C. Find the necessary charge on a 2.70 gram ping-pong ball so that the ball could levitate' in this field. In other words, the upward electrical force would just balance the downward gravitational force. Would the acquired charge need to be positive or negative?
