downward force on water drop = mass * acceleration due to gravity
let the electric field strength be applied vertically upwards to oppose gravity.
electric force = charge * electric field strength
0.0000001 kg * 9.81 m/s² = 1.6 * 10⁻¹⁹ C * E
E = 6.13 * 10¹² Newton/Coul

electric force = charge * electric field strength
0.0000001 kg * 9.81 m/s² = 1.6 * 10⁻¹⁹ C * E
E = 6.13 * 10¹² Newton/Coul
