Question

Assume that a honeybee is a sphere of diameter 1.010 cm with a charge of 46.0 pC uniformly spread over its surface. Assume also that a spherical pollen grain of diameter 40.7 ?m is electrically held on the surface of the sphere because the bee's charge induces a charge of -1.00 pC on the near side of the sphere and a charge of 1.00 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 1.025 mm from the center of the grain to the tip of a flower's stigma and that the tip is a particle of charge -46.0 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 (type 0) or does it move to the stigma (type 1)?
