Grade 12Electrostatics
- 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?
