Homework assignments
Instructions:
You will be assigned two problems per class to be handed in for credit. The following instructions must be obeyed exactly.
1. On the class sign-in sheet, alongside your name there is a number, 1, 2, 3, ... etc. You will use this number for the whole semester (If you were in the class last
semester, your number has probably changed.).
2. Each assigned problem will be taken from the textbook, but one of the input numbers is replaced by a formula, so that you can calculate the value from your
personal number. In this way, each student has a different value to work with.
3. Solve the problem, using your own input value, and calculate the answer to five significant figures, however many figures the numbers are given to in the
problem.
4. The problems for each class will appear as an "Assignment" in Sakai. I suggest you work out the problem before logging on to Sakai. You will submit your
answers on-line.
5. Your answer must be submitted before the next lecture. No late answers will be accepted.
6. Unless otherwise instructed, use the same units given in the problem e.g. if distances are given in meters use meters and use the values for the physical
constants given inside the back cover of the text book.
Example: Problem 21-2. A particle of charge +3.00 x 10-6 C is 12.0 cm distance from a second particle of charge -1.50 x 10-6 C. Calculate the magnitude of the
electrostatic force between the particles.
Your instructions are to replace 3.00 x 10-6 C with (2.00 + n/50) x 10-6 C. If you are number 37 on the class list, (2.00 + n/50) is (2.00 + 37/50) = 2.74. So you
would work the problem using 2.74 x 10-6 C instead of 3.00 x 10-6 C.
