Neco Model Questions Vol1 2022 Physics Question 41
Practice objective / multiple choice question 41 from the 2022 Neco Model Questions Vol1 Physics examination.
Two point charges are placed on the x‑axis. A charge \(+Q\) is at the origin and a charge \(-2Q\) is at \(x = d\). Given \(Q = 5\;\mu\text{C}\) and \(d = 0.20\;\text{m}\), (a) determine the position on the x‑axis between the charges where the net electric field is zero, and (b) calculate the electric potential at that point relative to infinity. Give your answer for the potential in volts (use \(k = 9.0\times10^{9}\;\text{N·m}^{2}\text{/C}^{2}\)).
