What is mean by Electric field lines ?

Assertion: A point charge is brought in an electric field. The field at a nearby point will increases whatever be the nature of the charge. Reason : the electric field is independent of the nature of charge.

The following pictures depict electric field lines for various charge configurations. (i) In figure (a) identify the signs of two charges and find the ratio |(q_(1))/(q_(2))| (ii) In figure (b) calculate the ratio of two positive charges and identify teh strength of the electric field at three points A, B and C (iii) Figure (c) represents the electric field lines for three charges . If q_(2) =-20nC then calculate the values of q_(1) and q_(3)
