Worked practice questions

For a point charge, all the charge is assumed concentrated at:

  1. Many points
  2. One point
  3. Two points
  4. Four points
Show answer and solution

Correct answer: B. One point

1. The extended body is replaced by an idealised one. 2. Its entire charge content is gathered together. 3. That charge sits at one point in space. _Source: syllabus Physics Part I, Chapter 1, Electric Charges and Fields._

Charges in a system are combined by adding them:

  1. Vectorially
  2. Graphically
  3. Algebraically
  4. Geometrically
Show answer and solution

Correct answer: C. Algebraically

1. Each charge carries its own sign, positive or negative. 2. Those signs must be respected in the sum. 3. So the charges are added algebraically. _Source: syllabus Physics Part I, Chapter 1, Electric Charges and Fields._

Electric charges add up in the same way as:

  1. Real vectors
  2. Real matrices
  3. Real tensors
  4. Real numbers
Show answer and solution

Correct answer: D. Real numbers

1. Charge has size but no direction of its own. 2. It behaves in a sum like an ordinary number. 3. So charges add up like real numbers, as scalars. _Source: syllabus Physics Part I, Chapter 1, Electric Charges and Fields._
