A parallel plate capicitaor with plates of area `1m^2` each, are at a separation of `0.1`m. If the electric field between the plates is 100 `N//C`, the magnitude of charge on each plate is : (Take `epsilon=8.85xx10^-12(C^2)/(N-m^2)`)

Options

A. `8.85xx10^(-10)C`
B. `9.85xx10^(-10)C`
C. `7.85xx10^(-10)C`
D. `6.85xx10^(-10)C`

Answer

A

Explanation

`d=0.1M" , "A=1M^(2)`
`E=(Q)/(Ain_(0))` , , `Q=Eaepsi_(0)=100xx1m^(2)xx8.85xx10^(-12)=8.85xx10^(-10)C`.
