A 1 C charge is placed at the origin with a 2 C charge placed at the coordinates (2,0). Where should a charge of -4 C be placed such that the net force on that charge is zero

(a) calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 10.0 g. silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. (b) imagine adding electrons to the pin until the negative charge has the very large value 1.00 mc. how many electrons are added for every 109 electrons already present
