Question 244

Students are asked for a statement about electric fields.

Three statements are listed.

  1. An electric field is described as a region in which an electric charge experiences an electric force.
  2. The direction of an electric field at a point is the direction of the force on a negative charge at that point.
  3. The relative strength of an electric field is shown by the spacing of the electric field lines.

Which statements are correct for electric fields?

A

1, 2 and 3

B

1 and 3 only

C

2 and 3 only

D

1 only
