ANSWER:

Prelecture Concept Question 23.03

Part A

A positive charge is moved from point A to point B along an equipotential surface. How much work is performed or required in moving the charge?

ANSWER:

The potential at the surface is higher then the potential at the center.

The potential at the center of the sphere is zero.

The potential at the center of the sphere is the same as the potential at the surface.

The potential at the center is the same as the potential at infinity.

The potential is highest at the center of the sphere.

The potential energy associated with the charge decreases.

The electric field does positive work on the charge.

The potential energy associated with the charge increases.

The electric field does negative work on the charge.

The electric field does not do any work on the charge.

The amount of work done on the charge cannot be determined without additional information.

Work is both performed and required in moving the charge from point A to point B.

Work is required in moving the positive charge from point A to point B.

No work is performed or required in moving the positive charge from point A to point B.

Work is performed in moving the positive charge from point A to point B.

Prelecture Concept Question 23.06

Part A

Which of the following statements are true?

Check all that apply.

ANSWER:

Problem 23.06

Part A

A +4.0 μC-point charge and a -4.0-μC point charge are placed as shown in the figure. What is the potential difference, A - B, between points and ? ( = 1/4π = 8.99 × 109 N · m2/C2)

ANSWER:

An equipotential surface is a three-dimensional surface on which the electric potential is the same at every point.

Electric field lines and equipotential surfaces are always mutually perpendicular.

The potential energy of a test charge decreases as it moves along an equipotential surface.

When all charges are at rest, the surface of a conductor is always an equipotential surface.

The potential energy of a test charge increases as it moves along an equipotential surface.
