SUMMARY
The electric potential energy between two electrons separated by 2.43 nm is calculated to be 1.185 J, while doubling the separation results in a potential energy of 0.95 J. The formula used is derived from the electric potential energy equation, which is V = kq/r, where k is Coulomb's constant, q is the charge of the electrons, and r is the separation distance. The correct approach involves using kq²/r to account for both charges in the system.
