The parallel plates of a capacitor have ...

The parallel plates of a capacitor have an area `0.2 m^2` and are `10^(–2)` m apart. The original potential difference between them is 3000 V, and it decreases to 1000 V when a sheet of dielectric is inserted between the plates filling the full space. Compute :
` ( in _0 =9xx 10 ^(-12) S.I ` units )
Permittivity of the dielectric.

A

` 25 xx 10^(12) C ^(2) N^(-1) m^(-2)`

B

` 37xx 10 ^(12) C^(2) N^(-1) m^(-2)`

C

` 27xx 10 ^(-12) C^(2) N^(-1)m^(-2) `

D

` 28xx 10^(-12) C^(2) N^(-1)( m^(-2 )`
