Igcse Model Questions Vol1 2022 Physics Question 12
Practice objective / multiple choice question 12 from the 2022 Igcse Model Questions Vol1 Physics examination.
Two point charges are placed on the x‑axis. Charge \(Q_{1}=+8.0\ \mu\text{C}\) is at the origin and charge \(Q_{2}=-2.0\ \mu\text{C}\) is at \(x=0.12\ \text{m}\). (i) Find the position \(x\) (in metres, measured from the origin) where the net electric field on the axis is zero. (ii) If \(Q_{2}\) is moved to \(x=0.20\ \text{m}\) while \(Q_{1}\) remains at the origin, find the new position where the net electric field is zero. Give your answers to three significant figures.
