Chapter 16: Q17Q (page 663)

A Student said, 鈥淭he electric field at the center of a charged spherical shell is zero, so the potential at that location is also zero.鈥� Explain to the student why this statement is incorrect.

Short Answer

Expert verified

The potential is not always zero but can be continuous when electric field is zero. statement is incorrect

Step by step solution

01

Concept/Significance of electric field.

An electric field is a mathematical construct that represents the amount and direction of the net electrical force experienced by a unit of electrical charge at a particular place in space as a result of interaction with all other electrical charges in the area.

02

Explanation of the incorrect statement

The electric potential is not necessarily zero when there is no electric field, but potential will be continuous. The potential is identical to that which can be seen on the surface of sphere. There would be no possible difference between the surface and center of the sphere.

Thus, the potential is not always zero but can be continuous when electric field is zero. statement is incorrect

In a region with an uniform electric field, you measure a potential difference of from the origin to a position of (0,0,10) m. Now we add a uniformly charged, thin spherical plastic shell centered at the origin. The spherical shell has a radius of 5 m and a charge of -3530 nC. Draw a diagram to help answer the following questions: (a) What is the potential difference from the origin to a position of (0,0,5) m (at the surface of the spherical shell)? (b) What is the potential difference from the position of (0,0,5) m to a position of (0,0,10) m ?

The diagram in Figure 16.74 shows three very large metal disks (seen edgewise), carrying charges as indicated. On each surface the charges are distributed approximately uniformly. Each disk has a very large radius R and a small thickness t. The distances between the disks are a and b, as shown; they also are small compared to R. Calculate V2-V1, and explain your calculation briefly.

If throughout a particular region of space the potential can be expressed as V=4xz+2y-5z, what are the vector components of the electric field at location (x,y,z)?

Question: At a particular instant an electron is traveling with speed (6000 m/s) . (a) What is the kinetic energy of the electron? (b) If a proton were traveling at the same speed (6000 m/s), what would be the kinetic energy of the proton?

A small metal sphere of radius r initially has a charge q0 . Then a long copper wire is connected from this small sphere to a distant, large, uncharged metal sphere of radius R. Calculate the final charge q on the small sphere and the final charge on the large sphere. You may neglect the small amount of charge on the wire. What other approximations did you make?
