IP 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 . 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. R = nothing m Request Answer 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 ? 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 ? Increased Decreased Request Answer Part C Complete previous part(s) Part D Find the radius of the plates that gives a capacitance of 1.8 μF for a plate separation of 3.0 mm . Express your answer using two significant figures. R = nothing m Request Answer Provide Feedback
