Field and potential in a capacitorA capacitor is made of two very large disks of radius R carrying uniformly distributed charges QA = Q and QB = -Q. The plates are parallel and 0.1 millimeters apart. The potential difference between the plates is VB - VA = -10 volts.What is the direction of the electric field between the disks?1(b) Invent values of Q and R that would make VB - VA = -10 volts.
