Figure shows the electirc field lines for two point charges separated by a distance. What are the signs of `q_(1) and q_(2)` ? Can you determine the ratio `q_(1)|q_(2)` ?

As the electric field lines emmante from `q_(1)` and some of them end at `q_(2)`, therefore `q_(1)` , must be a positive charge and `q_(2)` must be a negative charge. As the number of lines leaving `q_(1)` is twice the number of field lines terminating on `q_(2)`, therefore, magnitude of `q_(2), i.e., q_(1)|q_(2) = 2.`
