Asked by Sasha

Coulomb measured the deflection of sphere A when spheres A and B had equal charges and were a distance d apart. He then made the charge on B one-third the charge on A. How far apart would the two spheres then have had to be for A to have had the same deflection that it had before?

(9.0e^9)(1)(1)/(1)^2 = 9.0e^9
(9.0e^9)(1/4)(1) = 2.25e^9
2.25e^9/(1/2)^2 = 9.0e^9
1/2*d
