(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 – 45.0pC.
(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?
