You are given two metal spheres mounted on portable insulating supports. Find a way to give them equal and opposite charges. You may use some wire and a glass rod rubbed with silk but may not touch the rod to the spheres. Do the spheres have to be of equal size for your method to work? In Question 1, find a way to give the spheres equal charges of the same sign. Again, do the spheres need to be of equal size for your method to work?
