A Gaussian surface contains two charged spherical conductors -A and B, having radii of 3 mm and 2 mm respectivley. If their respective surface charge densities are 10muC//m^(2) and -5muC//m^(2) , then the total normal electric induction over the Gaussian surface will be

`5.8xx10^(-10)C`

`7.8xx10^(-10)C`

`8.8xx10^(-10)C`

`3.8xx10^(-10)C`
