PHY 102 ELECTROSTATICS Objective Question
Take CBT

Question

What is the total work done in moving a charge in a complete cycle within a conservative electrostatic field?
Options
A Positive, equal to the net potential energy.
B Negative, equal to the net kinetic energy.
C Zero.
Correct Answer
D Dependent on the path taken.
Correct Answer

Option C is the correct answer.

Detailed Explanation

The document explains that 'the work done in a cycle is zero. That is, if the initial point is the same as the final, the work done is zero.' (page 15, and also page 16 in the example explanation).

Hint

For a conservative field, if the start and end points are the same, what is the net work done?
