(1) Oil droplets are introduced into the space between two flat horizontal plates 5.0mm apart.
The plates voltage is then adjusted to exactly 780V so that one of the droplets is held
stationary. Then the plate voltage is switched off and the selected droplet is observed to fall
a measured distance of 1.50mm in 11.20s. Find the mass and the charge on the droplet
