Two 2.7 cmcm -diameter disks face each other, 2.2 mmmm apart. They are charged to ±15nC±15nC.

1.)What is the electric field strength between the disks?

2.)A proton is shot from the negative disk toward the positive disk. What launch speed must the proton have to just barely reach the positive disk?

Two large, thin, metal plates of 0.5mx0.5m face each other. They are spaced 2cm apart and have equal but opposite charges on their inner surfaces. a) if the magnitude E of the electric field between the plates is 700 N/C what is the magnitude of the charge on each plate? b) Integrate E across the gap between the plates to find the potential difference V and hence the capacitance C. c) Recalculate C using the parallel plate capacitator formula instead....
