Igcse Model Questions Vol1 2020 Physics Question 22
Practice objective / multiple choice question 22 from the 2020 Igcse Model Questions Vol1 Physics examination.
A fixed point charge \(Q = +8 \;\mu\text{C}\) is located at the origin. A small sphere of mass \(0.010 \text{ kg}\) and charge \(q = -2 \;\mu\text{C}\) is released from rest at point \(A(0.20\text{ m}, 0)\). It moves under the electrostatic force only to point \(B(0, 0.10\text{ m})\) where it momentarily stops after compressing a spring attached to a wall. Find the speed of the sphere just before it contacts the spring (i.e. at point \(B\)). Use \(k = 9.0 \times 10^{9} \text{ N m}^2\!\,\text{C}^{-2}\).
