A student is able to isolate a single charged oil drop while performing a Millikan oil drop experiment in the physics laboratory. The oil drop, of mass 1.23 x 10-15 kg, is suspended between two horizontal parallel plates spaced 8.0 mm apart when a voltage of 120 V is applied to the plates such that the lower plate is negative and the upper plate is positive. (a) Does the oil drop have an excess or deficit of electrons? Explain. (b) Determine the actual number of excess or deficit electrons on the oil drop. (c) What would be the acceleration of the oil drop if the voltage across the plates were to be increased to 300 V?

(b) Determine the actual number of excess or deficit electrons on the oil drop.
(c) What would be the acceleration of the oil drop if the voltage across the plates were to
be increased to 300 V?
(d) What would be the acceleration of the oil drop if the voltage across the plates were set
to 0 V (in other words, the plates are turned off)?
