Question 1013508: Chi Ming is dusting the house and raises a cloud of dust particles as he wipes across a table. If two 4.0x10^-14 C pieces of dust exert an electrostatic force of 2.0x10^-12 N on eachother, how far apart are the dust particles at that time?

Coulomb's law states that
We are solving for the distance d in this case...so
2.0 x 10^-12 N = (8.99 x 10^9)(4.0 x 10^-14 C)^2 / d^2
gives us
d = .00268 m = 2.68 mm
