Abumblebee flying through the air picks up a net charge of +40 pc, due in part to the triboelectric effect (charge transfer by friction) from collision with small dust particles*. the presence of this positive charge on their bodies the bumblebees locate negatively charged flowers when foraging for pollen and nectar**. the natural electric field near the surface of the earth has an average magnitude of 120 n/c and is directed downward. the mass of a typical bumblebee is 0.10 grams. calculate the ratio of the coulomb force on the bee to the gravitational force on the bee. note that (1pc = 10^{-12} c)(1pc=10 βˆ’12 c). [for small number answers, use the scientific β€œe” notation : 0.0076 = 7.6e-3 ]
