A student wanted to repeat the famous Millikan experiment where a small charge was suspended by gravity and an electric field. In between two parallel plates, she sprayed a fine oil drop that was charged and after applying a voltage between the plates the oil drop was suspended as shown below. The mass of oil drop was found to be 4.2(10)-15 kg. The voltage applied to the plates was 180 V and the separation distance between the plates was 0.010 m. Follow the steps below to determine the charge on the drop. 1. Draw a free-body diagram showing the two forces acting on the drop on the diagram 2. Calculate the strength of the electric field acting between the plates. below 3. Since the oil drop is suspended, the force of gravity is perfectly balanced by the electrical force. Use this to calculate the charge on the oil drop. 4. The top plate is negatively charged and the bottom plate is positively charged. On the diagram below draw the electric field acting between the plates. 5. What is the sign of the charge? Circle the correct quality of the charge. positive negative
