PHY 102 ELECTROSTATICS Objective Question
Take CBT

Question

Which of the following statements is TRUE regarding an electrostatic field, based on the definition provided in the document?
Options
A The work done in moving a charge between two points depends on the path taken.
B The mechanical energy is conserved, and the work done in a complete cycle is zero.
Correct Answer
C The force must be parallel to the displacement for work to be zero.
D It is a non-conservative field, where mechanical energy is not conserved.
Correct Answer

Option B is the correct answer.

Detailed Explanation

On page 15, under 'WORK DONE IN AN ELECTROSTATIC FIELD', the document states: 'Recall this is a characteristic of a conservative field. Electrostatic field is a conservative field, which means that the mechanical energy is conserved. It also means there is a potential. ... the work done in a cycle is zero.'

Hint

Conservative fields have specific properties related to work and energy. Look for these characteristics on page 15.
