When a certain air-fi lled parallel-plate capacitor is connected across a battery, it acquires a charge of 150 mC on each plate. While the battery connection is maintained, a dielectric slab is inserted into, and fi lls, the region between the plates. This results in the accumulation of an additional charge of 200 mC on each plate. What is the dielectric constant of the slab?
