Calculating point charges and ratio of electrostatic force to weight

[zooboodoo]

Homework Statement

Measurements show that a honeybee in active flight can acquire an electrostatic charge on the order of 93 pC.

a)How many electrons much be transferred to produce this charge?
Ne = *
b) Supposing two bees, both with this charge, are separated by a distance of 12 cm. What is the magnitude of the electrostatic force between the these two bees? (You may treat the bees as point charges.)
FE= N *
5.399e-9 OKc) What is ratio of this electrostatic force to the weight of 0.14 gm bee?
FE/Fweight =
3.783e-7 NO

Homework Equations

The Attempt at a Solution

I got through the first two parts, but in order to calculate the ratio of the electro static force to the weight I simply tried Fe/Fweight, 5.39e-9 / .00014 = 3.856e-13
Is there a specific relationship between the forces that I should know before trying to proceed?
thanks

Nope. They are completely different kinds of force (except for the fact that, in freshman physics, they both obey the inverse square law).
