Assume that a honeybee is a sphere of diameter 1.000 cm with a charge + 60.0 pC uniformly spread over its surface . Assume also that a spherical pollen grain of diameter 40.0 mu Cis electrically held on the surface of the bee because the bee's charge induces a charge of 1.00 pC on the near side of the grain and a charge of 1+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 1.000 mm from the tip of a flower's stigma and that the tip is a particle of charge -60.0 pC. (b) What is magnitude of the net electrostatic force on the grain due to the stigma ? (c ) Does the grain remain on the bee or move to the stigma ? |
