# Tracing Electric Field Lines

Electricity and Magnetism Level 3

Consider two charges $$q_{1}>0$$ and $$q_{2}<0$$. An electric field line exits the positive charge $$q_{1}$$ at $$45$$ degrees and enters the negative charge $$q_2$$ at $$180$$ degrees. What is the ratio $$\frac{|q_{1}|}{|q_{2}|}$$?
