Question

3. At a particular location near the earths 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 on the piece of plastic? A -1.16e-005 C B +8.63e +004 C C-8.63e+004 C D +4.32e+004 C E +1.16e-005 CShow all steps and explanation.

    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?
