The Total solution for NCERT class 6-12
Figure 1.33 shows tracks of threecharged particles in a uniform electrostatic field. Give the signs of the threecharges. Which particle has the highest charge to mass ratio?
Opposite charges attract eachother and same charges repel each other. It can be observed that particles 1and 2 both move towards the positively charged plate and repel away from thenegatively charged plate. Hence, these two particles are negatively charged. Itcan also be observed that particle 3 moves towards the negatively charged plateand repels away from the positively charged plate. Hence, particle 3 ispositively charged.
