The two plates of a parallel-plate capacitor each have area 1.20 m2, are 4.50 mm apart, and initially have vacuum between them. You connect a power supply to the capacitor, charging it to 3.50 kV. Keeping the power supply connected, you insert a sheet of dielectric with dielectric constant 2.50 that fills the space between the plates. Find the new capacitance once you insert the dielectric.
