Chapter 22: Q. 12 (page 624)

You have two neutral metal spheres on wood stands. Devise a procedure for charging the spheres so that they will have opposite charges of exactly equal magnitude. Use charge diagrams to explain your procedure.

Short Answer

Expert verified

The following is the charge diagram.

Step by step solution

01

Content Introduction

On top of an insulating stand, a neutral conducting sphere is at rest. A negatively charged tube is brought close to the neutral sphere (without touching it). The electrons are forced to travel from the left to the right side of the sphere by the presence of the negatively charged tube.

02

Content Explanation

To charge the spheres evenly, the two spheres must be in contact, and then a charged rod must be held close to but without touching one of the spheres. Then separate the spherical from the rod and remove it. A negatively charged rod is shown in this diagram. The electrons will then transfer from the left to the right sphere, making them equally and oppositely charged.

Linear accelerator uses alternating electric fields to accelerate electrons to close to the speed of light. A small number of the electrons collide with a target, but a large majority pass through the target and impact a beam dump at the end of the accelerator. In one experiment the beam dump measured charge accumulating at a rate of -2.0 nC/s. How many electrons traveled down the accelerator during the 2.0 h run?
