I only need help with last two questions

Measurements show that a honeybee in active flight can acquire an electrostatic charge on the order of 90.3 pC. 1) How many electrons much be transferred to produce this charge? Ne 563600000 Submit + 2) Supposing two bees, both with this charge, are separated by a distance of 14 cm. What is the magnitude of the electrostatic force between the these two bees? (You may treat the bees as point charges.) FE N Submit + 3) What is the ratio of this electrostatic force to the weight of the 0. 13 gm bee? FE/Fweight = Submit +
