Identify the charge on the bidy with a question mark.

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)
