IP Consider a parallel-plate capacitor constructed from two circular metal plates of radius RR. The plates are separated by a distance of 1.4 mm .

Part A-

What radius must the plates have if the capacitance of this capacitor is to be 1.8 μF ?

Express your answer using two significant figures.

Part B-

If the separation between the plates is increased, should the radius of the plates be increased or decreased to maintain a capacitance of 1.8 μF ?

Part C-
