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

Answer:

b) Electric lines of force never intersect each other because at the point of intersection, two tangents can be drawn to the two lines of force. This means two direction of electric field at the point of intersection, which is not possible
