Chapter 20, Problem 17PE

SPEAR, a storage ring about 72.0 m in diameter at the Stanford Linear Accelerator (closed in 2009), has a 20.0-A circulating beam of electrons that are moving at nearly the speed of light. (See Figure 20.39.) How many electrons are in the beam?

Chapter 20, Problem 17PE, SPEAR, a storage ring about 72.0 m in diameter at the Stanford Linear Accelerator (closed in 2009),

Figure 20.39 Electrons circulating in the storage ring called SPEAR constitute a 20.0-A current. Because they travel close to the speed of light, each electron completes many orbits in each second.
