Dear Sai,

Your score in Exam 2 is 87 out of 100

Everything was right except

#1: Your way is right but COMPLICATED. It was meant to be done
using the Fundamental Theorem of Line Integrals, once you realize
that the vector field is CONSERVATIVE, then find the POTENTIAL function
(see answer key)
: -5 points

#5: You integrated over the WHOLE sphere. Apparently you did not
see the x,y,z>0 in the definition of the region
: -5 points

#10: right answer to a DIFFERENT question. I asked for the POINT, not the value
: -3 points


Best wishes,

  Dr. Z.
