- 10You hold a metal sphere that’s been positively charged, and yourfriend holds one too with the same charge. You approach one an-other and begin to feel apush back. You push harder, she pushes harder still, until you’re both pushing as hard as you can! Later, you estimate that you pushed with about 400N. If you guys can’t manage to bring the objects closer than 20cm, then what would you estimate the magnitudeof the charges on the spheres to be?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.
