Item 8 Learning Goal: To review the meaning of capacitance and ways of changing the capacitance of a parallel-plate capacitor. Capacitance is one of the central concepts in electrostatics. Understanding its meaning and the difference between its definition and the ways of calculating capacitance can be challenging at first. This tutorial is meant to help you become more comfortable with capacitance. Recall the fundamental formula for capacitance: C = Q/AVC, where C is the capacitance in farads, Q is the charge stored on the plates in coulombs, and AVC is the potential difference (or voltage) between the plates. In the following problems it may help to keep in mind that the voltage is related to the strength of the electric field E and the distance between the plates, d, by AVc = Ed. Part A What property of objects is best measured by their capacitance? the ability to conduct electric current the ability to distort an external electrostatic field the ability to store charge Submit Part…

Suppose a swarm of bees flies through a thunderstorm and they become charged to –10.0 µC each. If there are 5,000 bees in the hive, what is the total electric flux through the walls of the hive? a. b. The Hatfields and McCoys have a historic feud, and now they have physics degrees. Using the figure below, if the bees fly straight up out of the hive and Mr. Hatfield would like to deflect the bees toward Mr. McCoy, in what direction should he apply a magnetic field (into the page or out of the page)? Vbees "leaving x-axis Om 100m 200m Mr. Hatfield hive Mr. McCoy If the bees fly straight up at 0.5 m/s, and a 50 µT magnetic field is applied in the direction you indicated in part (b), what is the magnetic force that the bees experience? (Both strength and direction.) d. When the bees return to the hive they fly straight down into it. If the magnetic field is still applied in the direction of your answer to part (b), in what direction are the bees deflected?
