Question

Two uncharged spheres are separated by 2.20 m. f 4.80x 1012 electrons are removed from one sphere and placed on the other, determine the magnitude of the Coulomb force (in N) on one of the spheres, treating the spheres as point charges.

Answer 1

q = he = 4.8 times 10^12 times 1.6 times 10^- 19 q = 7.68 times 10^- 7 c F = kq^2/r^2 F = 9 times 10^9 times (7.68 times 10^- 7)^2/(2.2)^2 F = 1.1 times 10^- 3 N
