Question:
A capacitor having a capacitance of $100 \mu \mathrm{F}$ is charged to a potential difference of $50 \mathrm{~V}$.
(a) What is the magnitude of the charge on each plate?
(b) The charging battery is disconnected and a dielectric of dielectric constant $2.5$ is inserted. Calculate the new potential difference between the plates,
(c) What charge would have produced this potential .difference in absence of the dielectric slab,
(d) Find the charge induced at a surface of the dielectric slab.
Solution:
