A positively charged oil droplet remains in the electric field between two horizontal plates, separated by a distance 1 cm. If the charge on the drop is 3.2 x 10-19 C and the mass of the droplet is 10-14 kg what is the potential difference between the plates? Now if the polarity of the plates is reversed what is the instantaneous acceleration of the droplet?

Millikan measured the electron's charge by observing tiny charged oil drops in an electric field. Each drop had a charge imbalance of only a few electrons. The strength of the electric field was adjusted so that the electric and gravitational forces on a drop would balance and the drop would be suspended in air. In this way the charge on the drop could be calculated. The charge was always found to be a small multiple of 1.6e-19 C. Find the charge on an oil drop weighing 1.94 10-14 N and suspended in a downward field of magnitude 2.42 104 N/C. find E
