Figure shows the electric field lines around three point charges A, B and C . Which of the following charges are positive?

Figure shows some of the electric field lines due to three point charges q_, q_2 and q_3 of equal magnitude. What are the signs of each of the three charges?

Fig. shows some of the electric field lines due to three point charges arranged along the vertical axis. All three charges have the same magnitude. (a) What are the signs of each of the three charges? Explain your reasoning. (b) At what points(s) is the magnitude of the electric field the smallest? Explain your reasoning. Explain how the fields produced by each individual point charge combine to give a small net field at this point or points. (c ) Two point charges q and -q are placed at a distance d apart. What are the points at which the resultant electric field is parallel to the line joining the two charge? .
