Question

1. Suppose two negative charges –q each is placed at a distance “a” apart in air
a) Draw the electric lines of forces surrounding them (1)
b) Can two electric lines of forces intersect? justify your answer (1)

Answer 1

Given:

Two negative charges (-q) each is placed at a distance of "a" in air.

To draw and explain:

• Draw the electric field lines between the charges.

• Can two electric field lines intersect?

Diagram:

Refer to the attached photo to understand the disposition of the Electrostatic Field lines between the two charges.

Explaination:

Electrostatic Field lines cannot intersect because of the following reasons:

• If the field lines intersected , then two tangents could be drawn at the points of intersection.

• This would mean an external charge placed at that point would experience force in two directions , which is impossible.

• Hence , Electrostatic Field lines don't intersect.
