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

What radius must the plates have if the capacitance of this capacitor is to be 1.5 μF ?

If the separation between the plates is increased, should the radius of the plates be increased or decreased to maintain a capacitance of 1.5 μF ?
