Question

A spray-painter nozzle normally produces droplets of paint in a cone shaped beam of width 30 ̊. What do
you think would be the effect on the beam if each droplet were given a large positive charge as it left the
nozzle? Give your reasons.

Answer 1

If each droplet were given a large positive charge as it left the nozzle, the angular width of the cone-shaped beam will be greater and not varying because equally charged particles repel.
