Question

9. An electric field line is a curve drawn in such a way that the tangent
at each point on the curve gives the direction of electric field at that
point. The relative closeness of field lines indicates the relative strength
of electric field at different points; they crowd near each other in regions
of strong electric field and are far apart where the electric field is
weak. In regions of constant electric field, the field lines are uniformly
spaced parallel straight lines.
ant properties of field lines are: (1) Field lines are​

Answer 1

Answer:

Field lines are closed curves

Answer 2

Properties of electric field lines are

• 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.

• The electric field line starts from the positive charge and ends from negative charge.

• If the charge is single, then they start or end at infinity.

• The line curves are continuous in a charge-free region.
