H2 Physics · JC 2 · Medium · Coulomb’s law

Two identical small conducting spheres, each carrying charge

+2.5\times10^{-7}\,\text{C}

, are separated by

0.060\,\text{m}

in air. What is the magnitude of the electrostatic force between them? Take

1/(4\pi\varepsilon_0) = 9.0\times10^9\,\text{N m}^2\text{C}^{-2}
