8/11  My return to campus will be delayed until
      August 13.

7/28  The solutions for test 3 are now available
      at the Noble Library Copy Center.

7/18  The solutions for test 2 are now available
      at the Noble Library Copy Center.

7/16 Please note that there is an error on the HW schedule
     for the day of July 18.  All of the problems for 
     July 18 are about Magnetism and thus should be from 
     Chapter 29, not Chapter 28.

7/15 Problem P53 was inadvertently omitted from the online
     problems for July 10 - July 16.  I have now added it
     to that webpage.  It is also here.

CHAPTER 26
53.  A certain parallel-plate capacitor is filled with
     a dielectric for which Kappa = 5.5.  The area of
     each plate is 0.034 m^2, and the plates are
     separated by 2.0 mm.  The capacitor will fail
     (short out and burn up) if the electric field 
     between the plates exceeds 200 kN/C.  What is the
     maximum energy that can be stored in the capacitor?

7/10  The solutions for test 1 are now available
      at the Noble Library Copy Center.

7/05 Problem P88 was inadvertently omitted from the online
     problems for July 1 - July 8.  I have now added it
     to that webpage.  It is also here.

CHAPTER 25
88.  Three particles with the same charge q and same mass m 
     are initially fixed in place to form an equilateral 
     triangle with edge lengths d.  (a) If the particles 
     are released simultaneously, what are their speeds 
     when they have traveled a large distance (effectively 
     an infinite distance) from each other?  (Measure the 
     speeds in the original rest frame of the particles.)

     Suppose, instead, the particles are released one at a 
     time:  The first one is released, and then, when the 
     first one is at a large distance, a second one is     
     released, and then, when that second one is at a large 
     distance, the last one is released.  What then are the 
     final speeds of (b) the first particle, (c) the second 
     particle, and (d) the last particle?

7/02  The Old Tests, both with and without solutions,
      are now available in the Noble Library Copy Center.
