(a) Sketch the electric field lines in the vicinity of the charged insulator in Figure19.31. Note its non-uniform charge distribution.

(b) Sketch equipotential lines surrounding the insulator. Indicate the direction of increasing potential.

Electric Field: An electric field is an electric property that is connected with any location in space where a charge exists in any form. The electric force per unit charge is another term for an electric field.

Equipotential Lines: Equipotential lines are similar to contour lines on a map that trace equal-altitude lines. The "height" in this situation is electric potential or voltage. Equipotential lines run parallel to the electric field at all times.

(a)

The electric field lines in the vicinity of the charged insulator Is plotted as blue lines –

(b)

The equipotential lines are in red, along with the arrows pointing in the directions of increasing potential –

Hence, the electric field and equipotential lines are plotted.
