Igcse Model Questions Vol1 2017 Physics Question 4
Practice objective / multiple choice question 4 from the 2017 Igcse Model Questions Vol1 Physics examination.
A fixed point charge \(+Q = 5.0\ \mu\text{C}\) is located at the origin of an x‑axis. A particle of charge \(q = -2.0\ \mu\text{C}\) and mass \(m = 2.0 \times 10^{-3}\ \text{kg}\) is released from rest at point \(P\) which lies \(0.10\ \text{m}\) to the right of the origin. No other forces act. (a) Find the magnitude of the electric field at \(P\). (b) Find the initial acceleration of the particle. (c) Assuming the particle moves directly towards the fixed charge, determine its speed after it has travelled \(5.0\ \text{cm}\). Give the speed in \(\text{m s}^{-1}\) to two significant figures.
