An electric field of 4.0 mV/m is induced at a point 2.0 cm from the axis of a long solenoid (radius = 3.0 cm, 800 turns/m). At what rate is the current in the solenoid changing at this instant?
 a. 0.50 A/s
  b. 0.40 A/s
  c. 0.60 A/s
  d. 0.70 A/s
  e. 0.27 A/s

Question 2

A long solenoid has a radius of 4.0 cm and has 800 turns/m. If the current in the solenoid is increasing at the rate of 3.0 A/s, what is the magnitude of the induced electric field at a point 2.2 cm from the axis of the solenoid?
 a. 3.3  10-5 V/m
  b. 3.6  10-5 V/m
  c. 3.9  10-5 V/m
  d. 4.2  10-5 V/m
  e. 6.0  10-5 V/m

As many as 28% of hospitalized patients requiring mechanical ventilators to help them breathe (for more than 48 hours) will develop ventilator-associated pneumonia. Current therapy involves intravenous antibiotics, but new antibiotics that can be inhaled (and more directly treat the infection) are being developed.
