As a honey bee beats its wings and collides with particles in the air, it builds up a slight positive charge. On a clear day, the petals and pollen of flowers carry a slight negative charge. In still air, a Coulombic force helps draw the pollen toward the bee. Consider a particle of pollen with a mass of 327 fg carrying a charge of -21 fC. The pollen particle begins to rise when the bee is 1.2 cm directly above it. What is the charge on the bee in units of pC? approximate the bee as a point charge. Reminder: p is short for pico x10^{-12}, f is short for femto x10^{-15}
