Worked practice questions

Electrostatic field lines are drawn as curves that are:

  1. Crossed over
  2. Continuous
  3. Broken up
  4. Dotted out
Show answer and solution

Correct answer: B. Continuous

1. A field exists at every point along the line. 2. So the line cannot stop and restart. 3. The curves are continuous without any breaks. _Source: syllabus Physics Part I, Chapter 1, Electric Charges and Fields._

Electrostatic field lines start at charges that are:

  1. Neutral
  2. Imagined
  3. Positive
  4. Negative
Show answer and solution

Correct answer: C. Positive

1. The lines run from one kind of charge to the other. 2. They end at the negative charges. 3. So they start at the positive charges. _Source: syllabus Physics Part I, Chapter 1, Electric Charges and Fields._

An electric dipole is a pair of charges that are equal and:

  1. Identical
  2. Neutral
  3. Doubled
  4. Opposite
Show answer and solution

Correct answer: D. Opposite

1. The two charges are written as q and minus q. 2. They match in size but not in sign. 3. So they are equal and opposite. _Source: syllabus Physics Part I, Chapter 1, Electric Charges and Fields._
