Electrostatic Potential from Two Charges
- Find a formula for the electrostatic potential \(V(\vec{r})\) that is valid everywhere
in space for:
- Two charges \(+Q\) and \(+Q\) placed on the z-axis at \(z'=D\) and \(z'=-D\).
- Two charges \(+Q\) and \(-Q\) placed on the z-axis at \(z'=D\) and \(z'=-D\), respectively.
- Simplify your formulas for the special cases of:
- the \(x\)-axis
- the \(z\)-axis
- Discuss the relationship between the symmetries of the physical situations and the symmetries of the functions in these special cases.
