Solve the all parts of given problem:
Problem: The plates of a parallel-plate capacitor have a separation of 2.02 mm, and each has an area of 10.6cm2. Each plate carries a charge of magnitude 4.50 × 108 C. The plates are in vacuum.
Part I: What is the capacitance?
Part II: What is the potential difference between the plates?
Part III: What is the magnitude of the electric field between the plates?
I need help to determine the magnitude of the electric field between the plates.
