What would happen if charge balance did not exist in a solution? The force between two charges is given in the footnote on this page. Find the force between two beakers separated by 1.5 m of air if one contains 250 mL with 1.0 × 10-6 M excess negative charge and the other has 250 mL with 1.0 × 10-6 M excess positive charge. There are 9.648 × 104 coulombs per mole of charge. Convert force from N into pounds (0.224 8 pounds/N). Could two elephants hold the beakers apart?
