Question 149

A parallel-plate capacitor with square plates of side length L L\,L and plate separation d d\,d has air between its plates, giving a capacitance CCC.

A second capacitor has square plates of side length 3L and a plate separation of 4d4d4d. The gap between these plates is completely filled with a dielectric material of relative permittivity εr=8\varepsilon_r = 8εr​=8.

What is the capacitance of this second capacitor in terms of CCC?
