If you shine an ultraviolet light on the metal ball of a negatively charged electroscope (shown in Exercises 1 and 2), it will discharge. But if the electroscope is positively charged, it won’t discharge. Can you venture an explanation?
1. An electroscope is a simple device consisting of a metal ball that is attached by a conductor to two thin leaves of metal foil protected from air disturbances in a jar, as shown. When the ball is touched by a charged body, the leaves that normally hang straight down spread apart. Why? (Electroscopes ate useful not only as charge detectors but also for measuring the quantity of charge: the more charge transferred to the ball, the more the leaves diverge.)
Need help finding B(z) as described in the second image. Main problem attached for reference as well.
Could you please solve part 3 of this question:
Now consider the electron in a material with a gap of 5 eV. Because of the gap, in order to increase the electron's momentum, the electric field must increase the electron's energy by 5 eV, which is impossible without applying ultraviolet light. In this case, what is the electron's velocity after 10-5 s in the electric field?
