A 15-μF Air-Filled Capacitor Is Connected to a 50-V Voltage

Short Answer

A 15-μF air-filled capacitor is connected to a 50-V voltage source and becomes fully charged.The voltage source is then removed and a slab of dielectric that completely fills the space between the plates is inserted.The dielectric has a dielectric constant of 5.0.
(a)What is the capacitance of the capacitor after the slab has been inserted?
(b)What is the potential difference across the plates of the capacitor after the slab has been inserted?
