Physics
A parallel plate capacitor has capacitance C, when there is vacuum within the parallel plates. A sheet having thickness of the separation between the plates and relative permittivity K is introduced between the plates. The new capacitance of the system is :
A
rac{3KC}{2K + 1}
B
rac{CK}{2 + K}
C
rac{3CK^2}{(2K + 1)^2}
D
rac{4KC}{3K - 1}
