Tiny Droplets of oil acquire a small negative charge while dropping through a vacuum (pressure = 0) in an experiment. An electric field of magnitude 5.92x10⁴ N/C points straight down.

(a) One particular droplet is observed to remain suspended against gravity. If the mass of the droplet is 2.93x10⁻¹⁵ kg, find the charge carried by the droplet.
(b) Another droplet of the same mass falls 10.3 cm from rest in 0.250 s, again moving through a vacuum. Find the charge carried by the droplet
