Short Answer

Compare and contrast the Coulomb force field and the electric field. To do this, make a list of five properties for the Coulomb force field analogous to the five properties listed for electric field lines. Compare each item in your list of Coulomb force field properties with those of the electric field—are they the same or different? (For example, electric field lines cannot cross. Is the same true for Coulomb field lines?)

There are some properties for the Coulomb force field similar to each other and also there are some properties which are different to the properties for electric field lines. They are listed below.

Step 1: Electric field lines

Electric field lines are the imaginary lines around the charged particles which gives the direction of electric field at a point in space. The electric field lines for a positive point charge are always directed away from the charge while the electric field lines for a negative point charge are always directed towards the charge.

Step 2: Similarities between Coulombs force field and electric field

The similarities between Coulomb force field and electric field are:

  • The Coulombs force field lines and electric field never cross each other.
  • The closeness of the Coulomb force field lines and electric field lines determines the strength of the field.
  • The strength of Coulombs force field and electric field depends on the separation between the two points where charges are kept.

The electric field lines originate from the positive charges and terminates at negative charges, this is similar to that of the Coulomb force field lines.

Step 3: Differences between Coulomb force field and electric field

The difference between the two fields are:

  • The magnitude of Coulomb force field depends on the value of charge placed at the point where force needs to be calculated. On the other hand, electric field is independent of it.

Most popular questions for Physics Textbooks

(a) By what factor must you change the distance between two-point charges to change the force between them by a factor of \(10\)? (b) Explain how the distance can either increase or decrease by this factor and still cause a factor of \(10\) change in the force.

If you have charged an electroscope by contact with a positively charged object, describe how you could use it to determine the charge of other objects. Specifically, what would the leaves of the electroscope do if other charged objects were brought near its knob?

Can the belt of a Van de Graaff accelerator be a conductor? Explain.

What is the repulsive force between two pith balls that are 8.00cm apart and have equal charges of -30.0 nC ?

Consider identical spherical conducting space ships in deep space where gravitational fields from other bodies are negligible compared to the gravitational attraction between the ships. Construct a problem in which you place identical excess charges on the space ships to exactly counter their gravitational attraction. Calculate the amount of excess charge needed. Examine whether that charge depends on the distance between the centers of the ships, the masses of the ships, or any other factors. Discuss whether this would be an easy, difficult, or even impossible thing to do in practice.
