Question

A parallel plate condenser is filled with two dielectric area of each plate is a m square and the separation is tm the dielectric constants are given k2 respectively its capacitance in f is

Answer 1

The space between the parallel plates of capacitor is air: 
   capacitance = C₁

Now the space is filled by two slabs of equal width (d/2) and of same area A as that of the parallel plates.



If the dielectric slabs are occupying an area of A/2 and the entire width d, that means the dielectric slabs are side by side.  Then it is like two half-capacitors are connected in parallel.  So their capacitances add.

Answer 2
