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 10.0picoCoulombs, and is hovering 1.9mm above a pollen grain, which has a charge of ?1.0×10?2picoCoulombs. Treat both the bee and pollen as point charges.
A) What is the strength of the electrostatic force on the pollen grain?
B) If the pollen grain's mass is 3.2×10?9g,what is the strength of the gravitational force on the pollen grain?
C) Does the pollen have to be negatively charged to be attracted to the bee?
