Question

The plates of an air-filled parallel-plate capacitor with a plate area of 14.5 cm² and a separation of 9.20 mm are charged to a 140-V potential difference. After the plates are disconnected from the source, a porcelain dielectric with k = 6.5 is inserted between the plates of the capacitor.

What is the charge on the capacitor before and after the dielectric is inserted?
