Eight point charges of charge q each are placed on the right corners of a cube of side a. A solid neutral metallic sphere of radius `a//3` is placed with its center at the center of the cube. As a result, charges are induced on the sphere, which form certain patterns on its surface. What is the potential of the sphere?

A

`(-12)/sqrt3(Kq)/a`

B

`(18)/sqrt4(Kq)/a`

C

`-(8)/sqrt2(Kq)/a`
