A honey bec of mass 130 mg has accumulated a static charge of +2.1 pC. The bee is returning to her hive by following the path shown in the figure. Because Earth has a naturally occurring celectric field near ground level of around 100 V/m pointing vertically downward, the bee experiences an electric force as she flies. What is the change in the bee's electric potential energy, AUacerie, as she flies from point A (0 m, 0.3 m) to point B (5.3 m, 3.9 m)? Compute the ratio of the bee's change in electric potential energy to her change in gravitational potential cncrgy, AUclectrie/ AUgrav.
