Question

Honeybees accumulate charge as they fly, and they transfer charge to the flowers they visit. Honeybees are able to sense electric fields; tests show that they can detect a change in field as small as 0.77 N/C. Honeybees seem to use this sense to determine the charges on flowers in order to detect whether or not a flower has been recently visited, so they can plan their foraging accordingly. As a check on this idea, let's do a quick calculation using typical numbers for charges on flowers.What is the magnitude of the difference between the fields of the flowers? Express your answer with the appropriate units.

Answer 1

Difference between the fields,

dE = k (q1 - q2)/d^2

dE = (9 x 10^9) (40 x 10^-12 - 30 x 10^-12)/0.24^2

dE = 1.56 N/C
