Q4. (20 marks) A conducting loop in the shape of an equilateral triangle is in a time varying magnetic field 2/3 B = 20t V3 [T] (figure 4). Given GH = 2 [m], the resistance of the loop R = 10 [$2], find a) The magnitude and the direction of the current induced in the loop. b) The force acting on each side of the loop. c) The net force acting on the loop. o e RS Figure 4 Figure 5 Q5. (20 marks) The circuit in figure 5 has R = 100 [$2], L= 10 [ml], C= 10 [HF], v = 100cos(1000t) [V]. Sketch the phasors of v, iR, it, ic and e. Find ir, it, ic and e
