FIGURE 2 - a) A mist of droplets was sprayed. We will focus on two particular regions outlined in the figure.
b) Zoom on the central part of the mist. c) Zoom on droplet B.
We are now interested in the forces at the edge of the mist, for example, on the charge qâ in figure 2.
1. Calculate the magnitude of the force F34 exerted by charges q4 and q5 on charge qB
q4 = 30 pC is assumed to be 2 mm from the charge qB = 20 pC. The charge q5 = 25 pC is assumed to
be 1.5 mm from the charge qB. Don't forget to make a diagram to support your reasoning.
