Igcse Model Questions Vol1 2017 Physics Question 33
Practice objective / multiple choice question 33 from the 2017 Igcse Model Questions Vol1 Physics examination.
Two point charges are fixed on the \(z\)-axis: \(q_1=+8\) nC at the origin and \(q_2=-12\) nC at \(z=0.04\) m. A test charge \(q=+2\) nC is moved from point \(A\) at \(z=0.10\) m to point \(B\) at \(z=0.02\) m along the axis.\n(a) Find the work done by an external agent in moving the test charge from \(A\) to \(B\).\n(b) Determine the potential difference \(V_B-V_A\).\n(c) If the test charge is released from rest at \(A\), what speed does it acquire at \(B\)? (Assume its mass is \(1.0\times10^{-6}\) kg and neglect radiation.)
