Neco Model Questions Vol1 2025 Physics Question 17
Practice objective / multiple choice question 17 from the 2025 Neco Model Questions Vol1 Physics examination.
Three point charges are placed on a straight line. Charge \(q_{1}=+2\ \mu\text{C}\) is at the origin, \(q_{2}=-5\ \mu\text{C}\) is at \(x=0.10\ \text{m}\), and \(q_{3}=+3\ \mu\text{C}\) is at \(x=0.20\ \text{m}\). (i) Find the position(s) on the line where the net electric field is zero. (ii) Compute the electric potential at that position due to all three charges. Use \(k=9.0\times10^{9}\ \text{N·m}^{2}\!\!/\text{C}^{2}\).
