Solve the following problems on your own paper. Please:

• Show all work.
• Put a box around your final answer to each problem.
• Be sure proper significant figures (SF) used for all answers.
• Separate all solutions with a horizontal line on your paper.
• A random selection of four problems will be graded for 25 points each.
• Solutions for suggested odd problems can be seen by following links.
• Solutions for assigned problems will be linked from this page after the due date.

Chapter 19

#4

Answer a direction with respect to the page. For example, "toward the bottom of the page" or "into the page", etc.

#8

Find the velocity first using principles from Chapter 16. Answer with 3 SF.

#14

Answer with both magnitude and direction.

#18

Assume the wire is 1.00 meter long for simplicity. The only forces on the wire are gravity and the magnetic force. Similar to #20.

#26

Use concepts from Chapter 17 to find the resistance and current in the wire. The number of turns given is an exact number and shouldn't count in your consideration of how many SF the answer should have.

#28

Convert the energy to Joules first, then find the velocity. Ignore the gravitational pull from the Sun, which is much smaller than the other forces.

#30

Find the velocity using the method discussed in #29. Answer with 3 SF.

#38

Answer with both magnitude and direction. This is similar to problems like Chapter 16, #27 or Chapter 16, #49.

#40

The magnetic field due to the 3.00 A wire at point P will point 45 degrees above the -x direction.

#46

Solve for each part of the loop separately, then add the results.

#50

Be sure to work in mks units here.
