1. The problem statement, all variables and given/known data 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.) 2. Relevant equations Phi=E.A and ΔV=Workdone/charge=-E.D 3. 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.
