I need help answering please

Part A A 0.80-jum-diameter oil droplet is observed between two parallel electrodes spaced 11 mm apart. The droplet hangs motionless if the upper electrode is 228 V more positive than the lower electrode. The density of the oil is 885 kg/m What is the droplet's mass? Express your answer to two significant figures and include the appropriate units View Available Hint(s) m Value Units Submit Part B What is the droplet's charge?
