Question:medium
Five equal point charges with charge $Q = 10$ nC are located at $x = 2, 4, 5, 10$ and $20$ m. If $\varepsilon_0 = \left[\dfrac{10^{-9}}{36\pi}\right]$ F/m, then the potential at the origin ($x = 0$) is
Five equal point charges with charge $Q = 10$ nC are located at $x = 2, 4, 5, 10$ and $20$ m. If $\varepsilon_0 = \left[\dfrac{10^{-9}}{36\pi}\right]$ F/m, then the potential at the origin ($x = 0$) is
Show Hint
Potential is scalar, so directly add contributions without considering direction.
