Standing in an electric field in zero gravity for 1 year

Alice is living on a sphere that has zero gravity and that is in an inertial reference frame. However, she and the sphere have electrical charges that are such that if she jumps she will accelerate towards the sphere at 9.81 m/s² from the electric force between her and the sphere. Both Alice and the sphere continue to have the same electric charges for one year. Alice lives on the sphere for one year.

What effect does living on the sphere for one year have on Alice's sense of balance considering that even though she is living in zero gravity in an inertial reference frame she has to fight against the electric force between her and the sphere to stand? I mean, even though an electric force is not equivalent to gravity would it be close enough for her to maintain her sense of balance? If she was to jump off a cliff on the sphere would she feel the acceleration from the electric force and if so how would it differ from the normal feeling of acceleration considering that it isn't from the normal force?

Alice also has two liquids that are electrically charged. Liquid A has an charge density of +/-1 C/cm³ while Liquid B has a charge density of +/-2 C/cm³ with C being Coulombs but the charge of both liquids is opposite of the charge of the sphere. Liquid A also has a mass density of 2 g/cm³ while Liquid B has a mass density of 1 g/m³.

Considering that both liquids are under an electric force instead of a gravitational force is it the liquid with the greater charge density that sinks or the liquid with the higher mass density that sinks or does neither liquid sink?
