A parallel plate capacitor having capacitance C farad is connected with a battery of emf V volts. Keeping the capacitor cannected with the battery, a dielectric slab of dielectric constant K is inserted between the plates. The dimensions of the slab are such that it fills the space between the capacitor plates. Then,

Options

A. charge the capacitor plates remains the same
B. charge on the plates increases K times
C. potential difference between the plates decreases to `V//K`
D. all of these

Answer

B
