Initially, both metal spheres are neutral.

In a charging process, 1 × 1013 electrons are

removed from one metal sphere and placed on

a second sphere. Then the electrical poten-

tial energy associated with the two spheres is

found to be −0.061 J .

The Coulomb constant is 8.98755 ×

109 N · m2/C2 and the charge on an electron

is 1.6 × 10−19 C.

What is the distance between the two

spheres?

Answer in units of m.
