Igcse Model Questions Vol1 2023 Physics Question 8
Practice objective / multiple choice question 8 from the 2023 Igcse Model Questions Vol1 Physics examination.
An isolated conducting sphere of radius \(R = 0.040\ \text{m}\) is initially uncharged. A point charge \(+Q = 8.0\ \mu\text{C}\) is placed on the axis at a distance \(a = 0.10\ \text{m}\) to the right of the sphere's centre. The sphere is then grounded, allowing charge to flow. Determine the magnitude of the electric field at point \(P\) located \(0.20\ \text{m}\) to the left of the sphere's centre (on the same axis). Give your answer in scientific notation to two significant figures, and state the direction (towards the left or right).
