HELP ME IN CAPACITORS:
PROBLEM: A capacitor with square metal plates separated by air has a capacitance off 4 microcoulumb.
a) what does the capacitance become if the separation of the plate is doubled?
b) what is the capacitance if plates with the same separation as the original plates but whose sides are each two times longer than the original plates?
c) what does the capacitance become if a dielectric material of dielectric constant 1.5 is placed between the original plates?
