Worked practice questions

Potential is defined as work done per unit test charge so that the result:

  1. Does not depend on q
  2. Doubles with q
  3. Is always zero
  4. Depends on the path
Show answer and solution

Correct answer: A. Does not depend on q

1. The work on a test charge is proportional to q. 2. Dividing by q removes that dependence. 3. So the result is independent of q. _Source: syllabus Physics Part I, Chapter 2, Electrostatic Potential and Capacitance._

Which is physically significant, the actual value of potential or the potential difference?

  1. Only the sign
  2. The difference
  3. The actual value
  4. Neither of them
Show answer and solution

Correct answer: B. The difference

1. The zero of potential can be chosen freely. 2. Only changes in potential do work. 3. So the potential difference is what matters. _Source: syllabus Physics Part I, Chapter 2, Electrostatic Potential and Capacitance._

Bringing a unit positive charge from infinity to a point, without acceleration, measures the point's:

  1. Electrostatic potential
  2. Electric field strength
  3. Surface charge density
  4. Capacitance value
Show answer and solution

Correct answer: A. Electrostatic potential

1. Infinity is the chosen zero of potential. 2. The work done per unit charge from there is the definition. 3. It is the electrostatic potential at the point. _Source: syllabus Physics Part I, Chapter 2, Electrostatic Potential and Capacitance._
