Scalar Potential
Consider a cube of edge a. There is a point charge q at each corner. Find [tex]\phi[/tex] at the center of the face for which x=a.
The answer to the problem is [tex]\0.707*(q/\epsilon_0*a)[/tex] I have to use the the scalar potential equation, but I have been stuck on this problem for a while. I know that I have to consider the angle which is cos45 = 0.707. I am not sure I understand what they are asking in the problem. |

Consider the symmetry of the cube, and remember that the potential is the sum of the potential of each charge. There are 8 charges.

the "1 spot" on a dice cube ...
each charge contributes its own portion to the potential there, since it is not the same distance from each source. |
