Q. 104.6( 9 Votes )

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?




Answer :


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
