The switch in the circuit below is initially in the OFF position, as shown. It is automatically switched to the ON position for exactly 67.7 ms and then automatically switched back to the OFF position. Find the instantaneous voltage across the 2.0 Ω resistor exactly 33.3 ms after the switch is placed back in the OFF position.

An fully ionized carbon atom (6 protons + 6 neutrons) is moving with a velocity of 17.7 m/s in an east to west direction in a vacuum chamber, exactly 7.77 cm above a straight current-carrying cable.  The magnetic field from the current in the cable levitates the carbon nucleus as it flies above, so the particle does not fall as it moves horizontally. Calculate the current in the wire and give both the magnitude and direction.
