Textbook Question
Chapter 23, Problem 12PQ
CASE STUDY A person in Franklin’s time may have been able to provide the same advice we came up with in Example 23.2. However, an 18th-century person may have had a different reason for his or her advice. What part of that person’s explanation would be the same as ours? What would be different?

A charged particle moves through a velocity selector at constant velocity. In the selector, E = 1.0×104 N/C and B = 0.250 T. When the electric field is turned off, the charged particle travels in a circular path of radius 3.33 mm. Determine the charge-to-mass ratio of the particle.
A cosmic ray muon with the same charge as an electron is moving toward the ground at an angle of 25.0° from the vertical with a speed of 7.70 × 107 m/s. As it crosses point P, the muon is at a horizontal distance of 85.0 cm from a high-voltage power line. At that moment, the power line has a current of 19.5 A.
What is the DIRECTION of the force on the muon at the point P in the diagram?
