Assume that a honeybee is a sphere of diameter 1.003 cm with a charge of + 45.7 pC uniformly spread over its surface. Assume also that a spherical pollen grain of diameter 43.0 um is electrically held on the surface of the honeybee because the bee's charge induces a charge of -1.02 pC on the near side of the grain and a charge of + 1.02 pC on the far side. (a) What is the magnitude of the net electrostatic force on the grain due to the bee? Next, assume that the bee brings the grain to a distance of 1.028 mm from the tip of a flower's stigma (it is a distance between the tip of stigma and nearest point of the grain surface) and that the tip is a particle of charge 45.7 pC. (b) What is the magnitude of the net electrostatic force on the grain due to the stigma? (c) Does the grain remain on the bee or does it move to the stigma? (a) Number -2.73e-10
