Chapter 14: Q29P (page 580)

Which of the following could be reasonable explanations for how a piece of invisible tape gets charged? Select all that apply. (1) Protons are pulled out of nuclei in one tape and transferred to another tape. (2) Charged molecular fragments are broken off one tape and transferred to another. (3) Electrons are pulled out of molecules in one tape and transferred to another tape. (4) Neutrons are pulled out of nuclei in one tape and transferred to another tape.

2 and 3.

Step by step solution

01

Significance of the electric field for the invisible tape

The electric field is referred to as a type of electric property that is associated with different points in the space when the charge is present in different forms.

The electric field gives the reason for which the piece of the invisible tape gets charged.

02

Determination of the reason for which the invisible tape gets charged

As the electrons get transferred from one material to a different material, then as the valence shell鈥檚 electron of an object is loosely attached, then the shell is being completed by the electrons of other material. Hence, this is the way in which the electrons transfer.

Point 1 states that proton neutrons are being pulled out from the tape. However, this point is incorrect as a massive amount of energy is needed to pull out the proton and a tape cannot do it.

Points 4 states that the neutrons are being pulled out from the tape. However, this point is incorrect as a massive amount of energy is needed to pull out the neutron and a tape cannot do it.

Point 2 states that the charged molecular fragments are broken off one tape and transferred to another. This point is correct as it is easier to break the chemical bonding of the tape that requires less amount of energy which can be possible to charge a tape.

Point 3 directly resembles the above explanation as the electrons can be pulled out from the tape as less amount of energy is needed to pull them out from the tape. Moreover, the energy to pull out the electrons can be obtained only by rubbing the tapes.

Thus, points 2 and 3 are the reasonable explanation for how a piece of invisible tape gets charged.

Figure 14.69 shows a neutral, solid piece of metal placed near two points charges. Copy this diagram.

(a) On your diagram, show the polarization of the piece of metal.

(b) Then, at location A inside the solid piece of metal, carefully draw and label three vectors: (1) E鈫�1, the electric field due to -q1; (2) E鈫�2, the electric field due to +q2; (3) E鈫�3, the electric field due to all of the charges on the metal.

(c) Explain briefly why you drew the vectors the way you did.

Which statements about a neutral atom are correct? Select all that apply. (1) A neutral atom is composed of positively and negatively charged particles. (2) The positively charged particles in the nucleus are positrons. (3) The electrons are attracted to the positively charged nucleus. (4) Positively charged protons are located in the tiny, massive nucleus. (5) The radius of the electron cloud is twice as large as the radius of the nucleus. (6) The negatively charged electrons are spread out in a "cloud" around the nucleus.

: A thin, hollow spherical plastic shell of radius \({\bf{R}}\)carries a uniformly distributed negative charge \({\bf{ - Q}}\). A slice through the plastic shell is shown in Figure 14.95. To the left of the spherical shell are four charges packed closely together as shown (the distance \({\bf{s}}\) is shown greatly enlarged for clarity). The distance from the center of the four charges to the center of the plastic shell is \({\bf{L}}\) , which is much larger than \({\bf{s}}\left( {{\bf{L}} \gg {\bf{s}}} \right)\). Remember that a uniformly charged sphere makes an electric field as though all the charge were concentrated at the center of the sphere.

(a)Calculate the \({\bf{x}}\) and \({\bf{y}}\) components of the electric field at location B, a distance \({\bf{b}}\) to the right of the outer surface of the plastic shell. Explain briefly, including showing the electric field on a diagram. Your results should not contain any symbols other than the given quantities \({\bf{R,Q,q,s,L}}\), and \({\bf{b}}\)(and fundamental constants). You need not simplify the final algebraic results except for taking into account the fact that \({\bf{L}} \gg {\bf{s}}\).

(b)What simplifying assumption did you have to make in part (a)?

(c)The plastic shell is removed and replaced by an uncharged metal ball, as in Figure 14.96. At location Ainside the metal ball, a distance \({\bf{b}}\)to the left of the outer surface of the ball, accurately draw and label the electric field\({{\bf{\vec E}}_{{\bf{ball}}}}\) due to the ball charges and the electric field \({{\bf{\vec E}}_{\bf{4}}}\) of the four charges. Explain briefly.

(d)Show the distribution of ball charges.

(e)Calculate the \({\bf{x}}\) and \({\bf{y}}\) components of the net electric field at location A.

The mobility of Na+ions in water is5.2脳10-8(m/s)(N/C). If an electric field of2400N/Cis maintained in the fluid, what is the drift speed of the sodium ions?

Explain briefly why the attraction between a point charge and a dipole has a different distance dependence for induced dipoles (1/r5 ) than for permanent dipoles (1/r3 ). (You need not explain either situation in full detail: just explain why there is this difference in their behavior.)
