On a typical clear day, the atmospheric electric field points downward and has a magnitude of roughly 100 N/C. 4a. How does the electric field and the (positive) charge acquired affect the bee?  A.  As the bee collects pollen (and positive charge), its effective weight increases.  B.  As the bee collects pollen (and positive charge), its effective weight decreases. 4b.What is the (gravitational) weight of an 0.1 gram Bumblebee? 4c.After the bee has acquired a charge of 23 pC, what is the magnitude of the electric force that adds/subtracts to its effective weight?
