The distance between the plates of a parallel plate capacitor of capacitance C Is doubled Its new capacitance will be

Options

A. 2C
B. `1/2C`
C. `C^(2)`
D. 4C

Answer

B

Explanation

Capacitance of parallel plate capacitor,
`C=(epsilon_(0)A)/(d)`
where, A = area of plates
and d = distance between plates.
i.e. `C prop(1)/(d)`
If the distance between the plates of a parallel plate capacitor of capacitance C is doubled, then its new capacitance will be
`C.=(1)/(2)C`
