How much charge is needed for it to be suspended in the air

Reference no: EM13311886

The Earth has an electric field that points toward the center of the earth and that has a magnitude of 150 N/C. Small drops of water can suspend in this field if they carry enough electric charges (This is the reason for fogs). Suppose a single drop of water is a 0.05 mm diameter sphere. How much charge is needed for it to be suspended in the air? Are the charges positive or negativeT.
