Electric field intensity at a point is defined as

  • A.the flux passing through unit area surrounding that point
  • B.the charge enclosed by a unit volume surrounding that point
  • C.the force per unit positive charge placed there
  • D.the work done in bringing a unit charge to that point from infinity

Answer: C

Writing \( \mathbf{E} = \mathbf{F}/Q \) removes the test charge from the description and leaves a property of the source alone. The work per unit charge from infinity is the potential, which is a different and scalar quantity.
