A 15-uF capacitor is connected to a 50-V battery and becomes fullycharged. The battery is removed and a slab of dielectric that completely fills the spacebetween the plates is inserted. If the dielectric has a dielectric constant of 5.0:
A. what is the capacitance of the capacitor after the slab is inserted?
B. what is the voltage across the capacitor's plates after the slab is inserted?
