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 the three charges? Explain your reasoning.
(b) At what point(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.

Opposite charges attract each other and same charges repel each other. It can be observed that particles 1 and 2 both move towards the positively charged plate and repel away from the negatively charged plate. Hence, these two particles are negatively charged. It can also be observed that particle 3 moves towards the negatively charged plate and repels away from the positively charged plate. Hence, particle 3 is positively charged.

It can be observed that particles 1 and 2 both move towards the positively charged plate and repel away from the negatively charged plate. Hence, these two particles are negatively charged. It can also be observed that particle 3 moves towards the negatively charged plate and repels away from the positively charged plate. Hence, particle 3 is positively charged.The charge to mass ratio (emf) is directly proportional to the displacement or amount of deflection for a given velocity. Since the deflection of particle 3 is the maximum, it has the highest charge to mass ratio.
