Solve the all parts of given problem:
Problem: A parallel plate capicator has plates that are 2.25 mm apart. The space between the plates is filled with a paper dielectric and has an electric field of 9.31 x 104 V/m when the charge on each plate is 0.660 µC.
Part A: What is the capacitance of this capacitor?
Part B: What is the area of each plate?
Please help, completely confused!! Give steps if possible for above problem.
