Step 1

The area of plates is 6.50 x 10^{-2} m^{2}, the distance between the plates is 1.47 x 10^{-4} m, the permittivity of free space is 8.85 x 10^{-12} C^{2}/(N.m^{2}), the dielectric constant of air is 1.00 and the dielectric constant is 2.70.

(a)

In first case, the space in between the plates is filled with air. The expression for the capacitance of the capacitor is,

Step 2

Here, *k _{air} *is the dielectric constant of air,

Thus, the capacitance of the capacitor is,

Step 3

(b)

In figure (a), the space in between the plates is half filled with air and half filled with a material which is parallel to the pla...
