A square is 1.0 m on a side. Point charges of +4.0 C are placed in two diagonally opposite corners.
 
  In the other two corners are placed charges of +3.0 C and -3.0 C. What is the potential (relative to infinity) at the midpoint of the square? (k = 1/40 = 9.0  109 N  m2/C2 )
  A) 1.0  106 V B) infinite C) 1.0  105 V D) 0 V E) 1.0  104 V

Question 2

An electric current through a tungsten filament maintains its temperature at 2800 K. Assume the tungsten filament behaves as an ideal radiator at that temperature.
 
  If the radiating area of the filament is 2.0  10-6 m2, at what rate does it radiate energy? ( = 5.670  10-8 W/m2  K4, Wien displacement law constant is 2.90  10-3 m  K)
  A) 11.5 W B) 7.0 W C) 8.5 W D) 5.5 W E) 10 W

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
