1. The problem statement, all variables and given/known data Two small objects of equal mass 3.0g are placed a certain distance apart. How many electrons must be transferred from one to the other so that the electric force between them is equal to the gravitational force between them? 2. Relevant equations Coulomb's Law: F = K (|q1||q2|)/r^2 Gravitational Force: F= GMm/r^2 3. The attempt at a solution Well I assumed I was looking for a proportion between gravitational force and electric force which would allow me to decide the electrons necessary....so I attempted to set the two equations equal to each other, however, I really don't know what to do with this information or if it is even right. Could I get some advice on how to start appropriately.
