## Homework Statement

Consider a uniformly charged cube with uniform charge density

**ρ.The ratio of electrostatic potential at the centre of the cube to that of one of the corners of the cube is?**

A hint on how to approach the problem's solution would be appreciated.(whether to use gauss law or not etc.)

A hint on how to approach the problem's solution would be appreciated.(whether to use gauss law or not etc.)

## Homework Equations

Phi=E.A and

**ΔV=**Workdone/charge=-E.D

## The Attempt at a Solution

I tried to use Gauss law and symmetry argument to find electric field inside the cube,but failed.Help would be appreciated.
