Neco Model Questions Vol1 2025 Physics Question 45
Practice objective / multiple choice question 45 from the 2025 Neco Model Questions Vol1 Physics examination.
A point charge of \(+2.0\ \mu\text{C}\) is placed \(0.10\ \text{m}\) above the centre of an isolated neutral conducting sphere of radius \(0.05\ \text{m}\). After electrostatic induction, determine (a) the magnitude of the electric field at a point \(Q\) located \(0.20\ \text{m}\) above the centre of the sphere (along the same vertical line), and (b) the force on a test charge of \(-1.0\ \text{nC}\) placed at \(Q\). Give the electric field in \(\text{N\,C}^{-1}\) (upward positive) and the force in newtons, indicating direction.
