1.	A parallel plate capacitor with air inbetween the paltes has a capacitance of 8 pF. The separation between the plates is now reduced by half and the space between them is filled with a medium of dielectric constant 5. Calculate the new value of capacitance.
Answer» `C_(0) = (in_(0) A)/(d) = 8 pF` `C = K. (in_(0) A)/(d//2) = 2 KC_(0)` `= 2xx5xx8 pF` = 80 pF
