Questions
In Fig. 2, twо strаight cоnducting rаils fоrm а right angle. A conducting bar in contact with the rails starts at the vertex at t = 0 s and moves with a constant velocity of 0 . 800 m s along them. The rail resistance is 0 . 400 Ω and the conducting bar has negligible resistance. A magnetic field with B → = 0 . 350 T is directed into the page. Find (a) the induced electromotive force in the loop and (b) the magnitude and direction of the external force that must be applied on the conducting bar in order to maintain its constant velocity at t = 2 . 00 s . (c) What is the power of the external force at t = 2 . 00 s , and (d) how much work does the external force do from t = 0 s to t = 2 . 00 s ? (The mass of the bar can be ignored.) (e) How much electric energy is consumed by the rail resistance from t = 0 s to t = 2 . 00 s ? (The mass of the bar can be ignored.) t3_fig2_q12_spr2026.docx
