A small oil drop, carrying a negative charge, is falling in air with a uniform speed of 8.00 x 10-5 m/s between two horizontal parallel plates. The upper plate is maintained at a positive potential relative to the lower one. Draw a diagram showing all the forces acting on the drop, stating the cause of each force.

Use the following data to determine the charge on the oil drop.

Take g = 10 m/s2
