5.) Protons can be approximated as spheres with a radius of about 8.5 x 10-16 m. Using Coulomb's law (which we saw at the beginning of the year), calculate the force required for two particles with the charge of one proton to be this far apart. While not exact, this gives a sense for how much force must be applied for the first step of this process to occur. Note: you will have to look up a couple of values here .. units are important, so it's probably best to work in Sl units.
