A housefly walking across a clean surface can accumulate a significant positive or negative charge. In one experiment, the largest positive charge observed was +73 pC. A typical housefly has a mass of 12 mg. What magnitude and direction electric field would be necessary to “levitate” a housefly that has the maximum charge? Could such a field exist in air?
