Chapter 13: Q16P (page 540)

An electron in a region in which there is an electric field experiences a force of magnitude3.8×10-16N . What is the magnitude of the electric field at the location of the electron?

Short Answer

Expert verified

The magnitude of the electric field electron is 2.37×103N/C.

Step by step solution

01

Identification of given data

The given data can be listed below,

The magnitude of the force isF=3.8×10-16N

02

Concept/Significance of electric field.

The forces acting on charges in an electric field are calculated in an abstract method. While a field is undeniably real, it lacks the characteristics of a particle or a mass.

03

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

The electric field of an electron is given by,

E=Fq

Here, F is the force acting on the electron and q is the charge on the electron.

Substitute values in the above,

E=3.8×10-16N1.6×10-19C=2.37×103N/C

Thus, the magnitude of the electric field electron is 2.37×103N/C.

A particle with charge +1nC (a nanocoulomb is 1X10-9C) is located at the origin. What is the electric field due to this particle at a location <0.1,0,0>m?

Two identical permanent dipoles, each consisting of charges +qand -qseparated by a distance s, are aligned along the xaxis, a distance rfrom each other, wherer≫s(Figure 13.75). Show all of the steps in your work, and briefly explain each step. (a) Draw a diagram showing all individual forces acting on each particle, and draw heavier vectors showing the net force on each dipole. (b) Show that the magnitude of the net force exerted on one dipole by the other dipole is this:

F≈14πε06q2s2r4

Three nested hollow spheres have the same centre. The innermost sphere has the radius of 2 cmand carries a uniformly distributed charge of 6 nC(1 nC=1×10-9 C). The middle sphere has a radius of5 cm and carries a uniformly distributed charge of -4 nC. The outermost sphere has a radius of 10 cm and carries a uniformly distributed charge of 8 nC.(a) What is the magnitude of the electric field at a distance of 1 cmfrom the centre? (b)What is the magnitude of the electric field at a distance of 4 cmfrom the centre?(c) What is the magnitude of the electric field at a distance of 9 cmfrom the centre?

At a given instant in time, three charged objects are located near each other, as shown in Figure 13.57. Explain why the equation

FonQbydipole≈Q(14πε2qsr3)

cannot be used to calculate the electric force on the ball of charge +Q.
Figure 13.57

Consider Figure 13.59. Assume that the dipole is fixed in position. (a) What is the direction of the electric field at location A due to the dipole? (b) At location B? (c) If an electron were placed at location A, in which direction would it begin to move? (d) If a proton were placed at location B, in which direction would it begin to move? (e) Now suppose that an electron is placed at location A and held there, while the dipole is free to move. When the dipole is released, in what direction will it begin to move?
