Gce Model Questions Vol1 2019 Physics Question 50
Practice objective / multiple choice question 50 from the 2019 Gce Model Questions Vol1 Physics examination.
A rectangular conducting loop of width \(w = 0.20\) m and height \(h = 0.10\) m lies in a uniform magnetic field \(B = 0.5\) T directed into the page. The loop is initially completely inside the field. It is pulled horizontally out of the field region at a constant speed \(v\) so that the side of length \(h\) remains always perpendicular to the field lines while the opposite side exits the field. After \(t = 0.05\) s the induced emf measured around the loop is \(\varepsilon = 0.25\) V. The resistance of the loop is \(R = 2\) Ω. Determine (a) the speed \(v\) of the loop and (b) the total charge that flows through the loop during this interval.
