Question

Drawings I and II show two patterns of electric field lines.

  1. The electric fields in both I and II are produced. by negative charge located somewhere on the left and positive charges located somewhere on the right.
  2. In both I and II, the electric field is the same everywhere.
  3. In both cases, the field becomes stronger on moving from left to right.
  4. The electric field in I is the same everywhere, but in II, the electric field becomes stronger on moving from left to right.

hintHint:

The magnitude of electric field at a point can be determined by knowing how closely are the electric field lines packed at that particular point.

The correct answer is: The electric field in I is the same everywhere, but in II, the electric field becomes stronger on moving from left to right.


    The magnitude of electric field at a point can be determined by knowing how closely are the electric field lines packed at that particular point.

    In case 1: the field lines are equally spaced everywhere.
    In case 2: the field lines are spaced more closely in the right than in the left.

    In both cases, the field becomes stronger on moving from left to right.
