Bumblebees actively foraging in the field have been found to be electrically charged, due largely to air resistance as they fly. The charge carried with a bee, which can be as great as 93 pC (pico = 10-12), is thought to play a significant role in pollination—the bee can attract grains of pollen from a distance, like a charged comb attracting bits of paper. The force needed to detach pollen from an avocado stigma is 4.0 x 10-10N. Discover the maximum distance at which the electrostatic force among a bee and a grain of pollen is sufficient to detach the pollen. Treat the pollen and bee as point charges, and suppose that the pollen has a charge opposite in sign and equal in magnitude to the bee. Is this a large enough distance to be helpful to the bee in pollination?
