Figure shows tracks of three charged particles in a uniform electrostatic field. Give the signs of the three charges. Which particle has the highest charge to mass ratio?                  

Answer:

Unlike charges attract each other, therefore particle 1 and 2 are negatively charged whereas particle 3 has positive charge. Particle 3 gets maximum deflection so it has highest charge (e) to mass (m) ratio because deflection,
