Multiple choice (briefly explain) Q1.1A flexible wire loop is lying on aWire loopfrictionless table made trom aninsulating material. The wirecan slide arbund horizontallyon the table ànd change shapefreely, but it canhot movevertically. The loop s connected to a power supply, a switchand two terminals fixed tb the table as shown. When theSwitchswitch is closed, a current/ flow around the loop.Which of the following diagrams most closely represents thefinal shape of the loop after the switch is closed?(A)(B)(D)(C)Q1.2A straight wire 50 cm long carries a current of 200 A. Thewire is at right angles to a magnetic field of flux dênsity 0.8 T.Calculate the magnitude of the force on the wire.(A) 8.0 J(B) 80J(C) 8.0 N(D) 80 N

Q1.1 A flexible wire loop is lying on a -Wire loop frictionless table made trom an insulating material. The wire can slide arbunđ horizontally on the table ànd change shape freely, but it cannot move vertically. The loop s.connected to a power supply, a switch and two terminals fixed tb the table as shown. When the switch is closed, a current// flow around the loop. Switch Which of the following diagrams most closely represents the final shape of the loop after the switch is closed? (A) (B) (D) (C)
