A point charge causes an electric flux of `-1.0 xx 10^3Nm^2C^(-1)` to pass through a spherical Gaussian surface of 10.0 cm radius centered on the charge. If the radius of the Gaussian surface were three times, how much flux would pass through the surface ?

A

`3 xx 10^3 (Nm^2)/(C )`

B

`-1.0 xx 10^3 (Nm^2)/(C )`

C

`-3.0 xx 10^3 (Nm^2)/(C )`

D

`-2.0 xx 10^3 (Nm^2)/( C)`
