Model a pollen grain as a sphere of carbon \(0.10 \mathrm{~mm}\) in diameter. If two such grains, spaced \(1.0 \mathrm{~m}\) apart, were somehow stripped of all their electrons, leaving only the protons, what would be the force between them? Compare this force to the weight of an aircraft carrier, which is about \(9 \times 10^{8} \mathrm{~N}\). The density of carbon is \(2300 \mathrm{~kg} / \mathrm{m}^{3}\).
