Chapter 24, Problem 1CQ

The direction of the electric field shown in each part of Figure 24.5 is that produced by the charge distribution in the wire. Justify the direction shown in each part, using the Coulomb force law and the definition of E = F/q, where q is a positive test charge.

Expert Solution & Answer
Check Mark
To determine

The direction of the electric field shown in each part of Figure is that produced by the charge distribution in the wire.

Answer to Problem 1CQ

  1. The direction of the electric field is upward
  2. The value of electric field is zero.
  3. The direction of the electric field is downward
  4. The direction of the electric field is upward

Given info:

Justify the direction shown in each part, using the Coulomb force law and the definition of E=F/q, where q is a positive test charge?

College Physics, Chapter 24, Problem 1CQ , additional homework tip  1

Explanation:

Positive charge moves from positive to negative, so the direction of electric field in part a is towards upper direction.

The distances between the positive and negative charge in part b is zero, so the electric field value is zero, so there is direction.

Positive charge moves from positive to negative, so the direction of electric field in part c is towards downward direction.

Positive charge moves from positive to negative, so the direction of electric field in part a is towards upper direction.

Conclusion:

The direction of the electric field shown in each part of Figure is studied.
