Assuming that two charges of the same magnitude are separated by one meter, and have an attraction of one newton. What is the amount of charge needed to create this situation 18. How many elementary charges are needed to create this charge? 19. If this amount of charge were held on one plate of a parallel plate capacitor, at 12 V, what would the capacitance be? 20. How far apart would the plates have to be in order to create this capacitance? The plates have an area of 0.004 m2. Comment on the distance between the plates.
Background: A group of physics students try to discover the scale of forces on the microscopic level by trying to find out how much charge is needed for one newton of force.
