Two entangled fermions each have equal probabilities of being in one of two states (state 1 or state 2). The fermions are separated so that no forces act between them. One of the fermions is then studied and found to be in state 1.
 
  What is the probability that, when studied, the second particle will also be found in state 1?
  A) 0 B) 33 C) 67 D) 50 E) 100

Question 2

The potential energy for the formation of a hydrogen molecule can be approximated by U = -A + BR + C/R, where R is the nuclear separation. Given that A = -78.5 eV, B = 2.57  1011 eV/m , and C = 1.44  10-9 eVm.
 
  At what nuclear separation is the potential energy a minimum? A)
 
  1.9  10-11 m
  B)
 
  3.7  10-10 m
  C)
 
  7.5  10-11 m
  D)
 
  2.9  10-11 m
  E)
 
  5.1  10-10 m
