Neco Model Questions Vol1 2020 Physics Question 50
Practice objective / multiple choice question 50 from the 2020 Neco Model Questions Vol1 Physics examination.
Two point charges are placed on the x‑axis. A charge \(q_{1}=+8\ \mu\text{C}\) is at the origin and a charge \(q_{2}=-2\ \mu\text{C}\) is at \(x=0.12\ \text{m}\). (i) Find the position on the x‑axis where the net electric field is zero. (ii) Calculate the electric potential at that point relative to infinity. Use \(k=9.0\times10^{9}\ \text{N·m}^{2}\text{C}^{-2}\).
