True or False questions on Electric Fields

  1. T or F. The E-field, E, at a point in space is the same as the electric force at that point, except for a factor of q.

  2. T or F. E-field lines point from negative to positive charge.

  3. T or F. The E-field is a vector.

  4. T or F. Field lines are vectors.

  5. T or F. One can tell where an E-field is strong (in a diagram) by the density of field lines.

  6. T or F. Field lines always cross each other near equilibrium regions.

  7. T or F. If a positively charged particle is released in an electric field, its trajectory will always follow the field lines.

  8. What is a valid unit for E?
