Question

Properties of electric field lines -​

Answer 1

Answer:

Properties of an Electric Field -

Field lines never intersect each other.

They are perpendicular to the surface charge.

The field is strong when the lines are close together, and it is weak when the field lines move apart from each other.

The number of field lines is directly proportional to the magnitude of the charge.

Explanation:

Answer 2

Properties of Electric Field Lines-

i) Electric field lines originate from positive and terminate at negative.

ii) Electric field lines always originate or terminate perpendicular to the surface.

iii) The tangent at every point to electric field line gives direction of electric field at that point.

iv) No two electric field lines can ever intersect each other. Since, if they do so there will be two directions of electric field at that point and it is not possible.

v) The relative closeness of field lines gives an idea about intensity of electric field in that region, closer the electric field line, greater is the intensity of electric field.

vi) Electric field lines cannot have sudden break. In a charge free region, field lines are continuous curve existing up to infinity.

vii) Electric field lines cannot form closed loops.

viii) Electric field lines can never enter a metal body.

ix) Electric field lines try to contract longitudinally i.e. lengthwise which can explain attraction between two unlike charges.

x) Electric field lines exert lateral pressure on each other which can explain repulsion between two like charges.
