Chapter 13: Q18P (page 540)

An electron in a region in which there is an electric field experiences a force of magnitude 3.7脳10-16N . What is the magnitude of the electric field at the location of the electron?

Short Answer

Expert verified

The magnitude of the electric field at the location of electron is 2.3脳103N/C.

Step by step solution

01

Identification of given data

The given data can be listed below,

The electric force experienced by electron is,Fe=3.7脳10-16N

02

Concept/Significance of electric force.

All charged particles are subject to an electric force. The electric force is responsible for a wide range of occurrences, like making your hair stand up on a cold, dry day, and causing your car to start.

03

Determination of the magnitude of the electric field at the location of the electron

The electric field related to the charge of electron is given by,

E鈬赌=F鈬赌qe

Here,F鈬赌is the magnitude of force and qis the magnitude of charge on the electron whose value is1.6脳10-19C .

Substitute all the values in the above expression,

role="math" localid="1656914428005" E鈬赌=3.7脳10-16N1.6脳10-19C=2.3脳103N/C

Thus, the magnitude of the electric field at the location of electron is 2.3脳103N/C.

A dipole is centered at the origin and is composed of charged particles with charge +2e and -2e, separated by a distance 7脳10-10malong the y axis. The +2e charge is on the -y axis, and the -2echarge is on the +y axis. (a) A proton is located at<0,3脳10-8,0>m. What is the force on the proton due to the dipole? (b) An electron is located at<-3脳10-8,0,0>m. What is the force on the electron due to the dipole? (Hint: Make a diagram. One approach is to calculate magnitudes, and get directions from your diagram.)

You make repeated measurements of the electric fieldE鈫�due to a distant charge, and you find it is constant in magnitude and direction. At timerole="math" localid="1656916621351" t=0your partner moves the charge. The electric field doesn鈥檛 change for a while, but at timet=45nsyou observe a sudden change. How far away was the charge originally?

What are the magnitude and direction of the electric field E鈫�at location <20,0,0>cmif there is a negative point charge of 1nC(1脳10-9C)at location<40,0,0>cm? Include units.

What is the electric field at a location b鈬赌=<-0.1,-0.1,0>m, due to a particle with charge +3nC located at the origin?

Consider the situation in Figure 13.39. (a) If we double the distance d, by what factor is the force on the point charge due to the dipole reduced? (b) How would the magnitude of the force change if the point charge had a charge of +3Q? (c) If the charge of the point charge were -2Q, how would the force change?
