Q10 of 106 Page 119

Consider the situation shown in figure. What are the signs of q1 and q2? If the lines are drawn in proportion to the charge, what is the ratio q1/q2?




Lines of force are moving outwards from q2, hence q2 is positively charged: +q2. Lines of force are going into q1, hence q1 is negatively charged : -q1.
From the diagram, 18 lines of electric field come out of q2 and 6 lines of electric field get into q1.
Ratio of
Hence, If the lines are drawn in proportion to the charge then q1:q2= 1:3
