Measurements show that a honeybee in active flight can acquire an electrostatic charge on the order of 90.9 pC.
a)How many electrons much be transferred to produce this charge?
b) 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= 4.0*10^-7 NO
FE=k (q1) x (q2)/r2
k=8.99 x 10^9
90.9 pC = 9.09 * 10^-11 C
14 cm = .14 m
The Attempt at a Solution
I got part a but I cant get part b
I used Couloumb's equation and....
FE = k (9.09*10^-11)^2 / (.14)^2
and I got 4*10^-9 but it doesnt work where am i going wrong on this problem. Any help would be much appreciated. Thanks in advance.
