Honeybees acquire a positive charge while flying through the air. The rapid motion of the wings through the air provides the "friction" to strip charges off the bee, just like running a comb through your hair. Assume that a bee has acquired a charge of 12 pC(1 pico Coulomb = 10-12 C), and is hovering 1 mm above a pollengrain, which has a charge of -0.01 pC. Treating both the bee and pollen as pointchargesa. What is the force on the pollen grain?b. If the pollen grain’s mass is 3.8 x 10-9 g, is the forcesufficient to lift thegrain?c. Does the pollen have to be negatively charged to be attracted tothe bee?Explain.
