Unformatted text preview: front of you carries a current of 2 A in a direction to the west (your left) in a region with a magnetic field of 3 T that is also directed to the west. What is the magnitude and direction of the magnetic force on the wire? a. b. c. d. e. 60 N, east 60 N, south 60 N, up 60 N, down 0N 3. The triangular circuit in the figure is in a uniform magnetic field as shown. The current in the circuit is 10 A counterclockwise and the magnetic field is 0.5 T. The net force on the circuit is: a. b. c. d. e. Up. Down. Into the paper. Out of the paper. Zero. Multiple Choice continued(25 pts total, 5 pts each problem) (Please record answers on the provided bubble sheet.) 4. An initially uncharged capacitance C is connected in series with a resistance R to a battery with EMF V. When fully charged, the battery is disconnected from the circuit and replaced with a wire. After a time equal the time constant after the exchange, how much charge remains on the capacitor? a. b. c. d. e. None of the above. 5. A magnetic field is applied perpendicular to an artery. Which of the following statements is FALSE? a. b. c. d. e. All of the ions will drift toward the same side. Positive ions will drift to one side, negative to the other. In equilibrium, the electric and magnetic forces on an ion will balance. The equilibrium potential difference across the artery will be proportional to the flow rate. The equilibrium potential different across the artery will be proportional to the magnetic field....
