Physics · Electrostatics
In a region, there are parallel planes of equipotential surfaces where the potential changes by the same amount between adjacent planes. A positive charge 'q' is moved from a point A to a point B located on two different equipotential surfaces across different configurations with the same potential difference VB − VA. Which of the following statements is true regarding the work done?
- 1Minimum work is required to move q when the trajectory is a straight line.
- 2In all cases, the work done is the same.✓
- 3Maximum work is required to move q when the planes are further apart.
- 4Maximum work is required to move q when the planes are closer.
Correct answer
In all cases, the work done is the same.
