Document Summary
At time t = 0 the switch is ipped to position b, and remains there for a long time. Compare your answer to what charge was held by c1 at t = 0, just before the switch was ipped. Calculate the time constant, and label your axes properly. 2: [5] three very long current-carrying wires are shown in the gure, as well as locations. 3: [5] the gure shows a copper rod of length x = 75 cm suspended by two springs to balance its weight (the springs are attached using plastic hooks). Now you connect exible low-mass electric contacts at points p1 and. P2, and drive a current through the rod by connecting p1 to the negative terminal, and p2 to the positive terminal of a powerful battery. Explain! (b) calculate by how much the rod is displaced. 4 v(tf) = v(ti) +(cid:82) tf vf = vi + a t f (t) = t df a(t) dt.
