Hi Everyone,

     Sorry I am a little late getting this posted.  Gary's response to last week's question was correct.  His observation regarding GRE questions was also generally true.  Many GRE questions can be answered without doing a lot of calculations.  Here's this week's question.

Which of the following functions could represent the radial wave function for an electron in an atom?  (r is the distance of the electron from the nucleus, A and b are constants)

I. Aexp(-br)

II. Asin(br)

III. A/r

A. I only

B. II only

C. I and II only

D. I and III only

E. I, II, and III
