Neco Model Questions Vol1 2022 Physics Question 28
Practice objective / multiple choice question 28 from the 2022 Neco Model Questions Vol1 Physics examination.
Two point charges are fixed in the xy‑plane. Charge \(q_{1}=+2\ \mu\text{C}\) is at the origin \((0,0)\) and charge \(q_{2}=-3\ \mu\text{C}\) is at \((0,0.04\ \text{m})\). Find (i) the magnitude of the electric field at point \(P(0.03\ \text{m},0)\) and the angle it makes with the positive \(x\)-axis (measure the angle counter‑clockwise), (ii) the electric potential at \(P\) relative to infinity, and (iii) the work required to move a test charge \(+1\ \text{nC}\) from \(P\) to infinity. Give your answers as (i) \(E = \dots\ \text{N C}^{-1}\) at \(\dots^{\circ}\), (ii) \(V = \dots\ \text{V}\), (iii) \(W = \dots\ \text{J}\). Use \(k = 8.99\times10^{9}\ \text{N m}^{2}\text{C}^{-2}\).
