The inward and outward electric flux for...

The inward and outward electric flux for a closed surface unit of `N-m^(2)//C` are respectively `8xx10^(3)` and `4xx10^(3)`. Then the total charge inside the surface is [where `epsilon_(0)=` permittivity constant]

A

`4xx10^(3)`

B

`-4xx10^(3)`

C

`((-4xx10^(3)))/(epsilon_(0))`

D

`-4xx10^(-3) epsilon_(0)`

Text Solution

Verified by Experts

The correct Answer is:
D

Net flux `=-4xx10^(3)`
`=4xx10^(3)=q/(epsilon_(0)), q=-4xx10^(3)epsilon_(0)`
