Charges and Coulomb’s Law:  Identify if the statement is true or false.  1. When a metal plate is given a positive charge, protons are transferred to the plate from another object. 2. Two electrons placed near one another with no other objects close by will accelerate away from each other. 3. If two charges (big and small) touch each other, the small one will acquire more charge after separation. 4. If two spheres A and B with charges +6 µC and –6 µC touch each other, then the charge of each after  separation is zero
