Fungal spores develop a measurable charge when launched. Mycologists are unsure whether the repulsive force between spores aids in their dispersal. A typical spore is nearly spherical, with a diameter of 4 μmμm and a density equal to that of water. Each spore loses approximately 200 electrons during launch. Estimate to one significant figure the electric force between two spores whose centers are 10 μm apart.
