Neco Model Questions Vol1 2018 Physics Question 12
Practice objective / multiple choice question 12 from the 2018 Neco Model Questions Vol1 Physics examination.
Two point charges are placed on a vertical line. Charge \(q_{1}=+6\,\mu\text{C}\) is at the origin \(O\), and charge \(q_{2}=-3\,\mu\text{C}\) is at point \(P\) which is \(0.12\,\text{m}\) above \(O\). (a) Find the distance \(x\) from \(O\) along \(OP\) where the net electric field is zero. (b) Calculate the electric potential at that point relative to infinity.
