The figure below shows the electric field lines for two point charges separated
The figure below illustrates the electric field lines for two point charges separated by a small distance.
(a) Calculate the ratio ( q_1/q_2 ). Provide your answer as a decimal rounded to three significant figures.
(b) Determine the signs of ( q_1 ) and ( q_2 ). Are the charges positive or negative? Select the correct options: - ( q_1 ) is positive. - ( q_1 ) is negative. - ( q_2 ) is positive. - ( q_2 ) is negative.

Because there is 18 lines coming off of it, and only 6 reaching the second charge, you go 6/18 = 1/3 or 0.333
